Stuff to make using the site easier ..

I use abbreviations for many things:
Precip = Precipitation
SWS = Special Weather Statements
I will continue to add more to this list as I think of them.
I update the forecasts by 7AM and 7PM each day...more frequently if some weather thing is going on.

I am based in Peterborough, NH, but the main forecasts (for now) are for Nashua, NH and the region. I send out an email every Thursday that covers the upcoming weekend forecast. I also send out advisories when issued by the NWS to this list. You will NEVER get SPAM or emails from anyone else. I don't share my mail list with anyone. If you'd like to be a part of that mailing, send your email address to: Mail List

 

How I started...

I've been a weather hobbyist all of my life. As a child, I used to stand outside in the rain during thunderstorms just to watch the lightning. Back in the '70s getting weather information was a chore. I remember listening to NWS broadcasts during hurricane season and plotting these on a piece of paper. After moving to New England I finally bought my first real weather station made by Davis Instruments. I began to record daily weather data in a journal. I had a few people, where I work, who knew I was a weather nut, ask me to send them an e-mail on the weekend forecast. So two grew to five then 15, then 40, and now my Thursday weekend mail list reaches over 200+ people. I took some web programming classes in the late '90s and a few years after that RichLefko.com was born. I wanted to share my hobby with anyone who was interested, and I am quite overwhelmed with how many people seem to be interested. I've gotten so many "thank yous" for a variety of reasons..."saved my party", "saved my wedding", "saved my life." It's been fun and rewarding all at the same time.
Thanks for visiting RichLefko.com. Please tell your friends and family.

SITUATION OVERVIEW
------------------

Tropical Storm Isaias continues to track through New England, and
will more or less follow the Connecticut River Valley north through
this evening. Conditions will quickly deteriorate over the next
several hours from south to north, with the worst of the impacts
expected this evening.

Easterly winds will continue to strengthen this evening as they shift
to southerly across much of the area. Wind gusts of 40 to 50 mph are
expect, with locally higher gusts to 60 mph possible. This will be
capable of downing some trees and power lines. In addition, there
continues to be a threat for isolated tornadoes mainly across southern
New Hampshire and extreme southwestern Maine. Winds will begin to
diminish late this evening. Rainfall totals of 1 to 2 inches are still
expected in parts of the White Mountains and Connecticut River Valley.
With the more western track of Isaias the flash flooding threat has
diminished. Locally higher amounts in the higher terrain may lead to
flash flooding in complex terrain or poor drainage areas. Parts of the
forecast area near the coast may see less than 1 inch of rainfall.

In general, the coastal flooding threat remains low based on the
forecast forward speed of Isaias, with any inundation likely less than
a foot. Some splashover is expected during the high tide tonight.
Rough surf and an increased risk for dangerous rip currents will be
possible behind Isaias on Wednesday.

POTENTIAL IMPACTS
-----------------

* WIND:
Potential impacts from the main wind event are now unfolding across
Much of southern New Hampshire and southwestern Maine. Remain well
sheltered from dangerous wind having possible significant impacts. If
realized, these impacts include:
- Some damage to roofing and siding materials, along with damage
to porches, awnings, carports, and sheds. A few buildings
experiencing window, door, and garage door failures. Mobile
homes are damaged, especially if unanchored. Unsecured
lightweight objects become dangerous projectiles.
- Numerous large trees snapped or uprooted, leading to downed
power lines.
- Many roads are impassable from debris, caused by downed trees
and power lines. Many bridges, causeways, and access routes
impassable.
- Numerous power and communications outages likely.

Potential impacts from the main wind event are also now unfolding
across northern New Hampshire and the western Maine mountains.
Remain well sheltered from hazardous wind having possible limited
impacts.

* SURGE:
Little to no storm surge impacts are anticipated at this time across
New Hampshire and western Maine.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
the Connecticut River Valley and the White Mountains. Remain well
guarded against dangerous flood waters having possible significant
impacts. If realized, these impacts include:
- Moderate rainfall flooding may prompt several evacuations and
rescues.
- Rivers and tributaries may quickly become swollen with swifter
currents and overspill their banks in a few places, especially
in usually vulnerable spots. Small streams, creeks, canals, and
ditches will overflow.
- Flood waters can enter some structures or weaken foundations.
Several places may experience expanded areas of rapid
inundation at underpasses, low-lying spots, and poor drainage
areas. Some streets and parking lots take on moving water as
storm drains and retention ponds overflow. Driving conditions
will become hazardous. Some road and bridge closures.

Potential impacts from the flooding rain are still unfolding across
southern New Hampshire and western Maine. Remain well guarded against
locally hazardous flood waters having possible limited impacts.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across New
Hampshire and western Maine. Remain well braced against a tornado
event having additional limited impacts. If realized, these impacts
include:
- The occurrence of isolated tornadoes can hinder the execution
of emergency plans during tropical events.
- A few places may experience tornado damage, along with power
and communications disruptions.
- Locations could realize roofs peeled off buildings, chimneys
toppled, mobile homes pushed off foundations or overturned,
large tree tops and branches snapped off, shallow-rooted trees
knocked over, moving vehicles blown off roads, and small boats
pulled from moorings.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
Now is the time to remain safely sheltered from the storm. Stay
inside and away from windows. Listen for updates and be ready in case
you lose electrical power. Locate your battery powered radio and
flashlight from your Emergency Supplies Kit. Keep these items close.

During the peak of the storm, keep your shoes on and rain gear handy.
Boots and tennis shoes offer the best foot protection if you become
unexpectedly exposed to the elements.

Continue to keep your cell phone well charged for as long as
possible. If you lose power, use it more sparingly and mainly for
personal emergencies and check-ins. Do not overload communications
systems with idle chatter.

Do not be a thrill seeker or risk your life for senseless photos or
videos. Be wise and avoid becoming another statistic.

Be ready to move to the identified safe room if your home or shelter
begins to fail. Quickly move to an interior room on the lowest floor.
Put as many sturdy walls between you and the storm as you can.
Protect your head and body.

local National Weather Service forecast office.


DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Storm Isaias was
located by NOAA Doppler weather radars and surface observations near
latitude 42.7 North, longitude 74.2 West. Isaias is moving toward
the north-northeast near 40 mph (65 km/h), and this general motion
is expected through tonight. On the forecast track, the center of
Isaias will continue to move farther inland over eastern New York
and Vermont this afternoon and evening, and over southern Canada
tonight.

Data from Doppler weather radars along with surface observations
indicate that maximum sustained winds have decreased to near 65 mph
(100 km/h) with higher gusts. Gradual weakening is expected this
afternoon and evening, followed by a faster rate of weakening
tonight. Isaias is forecast to become post-tropical tonight or early
Wednesday.

Tropical-storm-force winds extend outward up to 205 miles (335 km)
from the center. During the past hour, a NOAA NOS observing site at
Sandy Hook, New Jersey, reported a sustained wind 41 mph (67 km/h)
and a gust to 50 mph (80 km/h). Wind gusts in excess of 50 mph (80
km/h) have also been reported at multiple sites in southeastern New
York, Connecticut, Rhode Island, and Massachusetts during the past
hour.

The estimated minimum central pressure based on surface
observations is 995 mb (29.39 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Isaias can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC,
and on the web at www.hurricanes.gov/text/MIATCDAT4.shtml.

STORM SURGE: The combination of storm surge and the tide will
cause normally dry areas near the coast to be flooded by rising
waters moving inland from the shoreline. The water could reach the
following heights above ground somewhere in the indicated areas if
the peak surge occurs at the time of high tide...

Sandy Hook NJ to Martha's Vineyard MA including Long Island Sound,
Block Island Sound, Narragansett Bay, Buzzards Bay, and Vineyard
Sound...1-2 ft

WIND: Widespread tropical-storm conditions are expected in the
tropical storm warning area in eastern New York, Long Island, and
southern New England, with wind gusts to hurricane force possible.
These winds could cause significant tree damage and power outages.

Tropical storm conditions are expected to reach southern New
England by late afternoon, and reach northern New England tonight.

Gale-force winds are expected to spread into southeastern Quebec
tonight and Wednesday. See products issued by Environment
Canada for more information.

RAINFALL: The following rainfall accumulations are expected along
and near the track of Isaias:

Eastern New York into Vermont: 2 to 4 inches, isolated maximum
totals 6 inches.

Western Connecticut, western Massachusetts, New Hampshire and
western Maine: 1 to 3 inches. Southern Quebec: 1 to 3 inches.

Heavy rainfall near the path of Isaias, through the Hudson River
Valley, is likely to result in flash flooding, particularly through
urban areas and the surrounding terrain of the Catskills, Adirondack
and Green Mountain Ranges through Tuesday night. Scattered minor to
moderate river flooding is likely across portions of the
Mid-Atlantic. Quick-responding rivers in the Northeast will also be
susceptible to minor and possible moderate river flooding.

TORNADOES: A couple of tornadoes are possible across southern New
England late this afternoon. A risk for tornadoes may continue and
spread across parts of northern New England through this evening.

SURF: Swells generated by Isaias will spread northward along the
mid-Atlantic and Northeast coasts of the United States today. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
