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. On weekends by 9AM.

I am based in Peterborough, NH, but the main forecasts (for now) are for Nashua, NH and the region. I send out an e-mail 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 e-mail from anyone else. I don't share my mail list with anyone.

What is a "ShortWave"?

Also known as Shortwave Trough; a disturbance in the mid or upper part of the atmosphere which induces upward motion ahead of it. If other conditions are favorable, the upward motion can contribute to thunderstorm development ahead of a shortwave.

MCS = Mesoscale Convective System (Bunch of thunderstorms)

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 you's" 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.

Rich's Local Weather Discussion:

6/17 -  9:37 AM: Happy Father's Day to my fellow Dads out there! I hope you enjoy your day. It will be a warm day with increasing humidity. The core of the heat arrives Sunday night and Monday. Heat indices on Monday could easily top the 100° mark. Record high air temps are also possible. A cold front will shift south through Quebec during Monday. This cold front moves south touching off strong to severe thunderstorm activity by Monday afternoon or evening. This will break the heat, but the storms could be damaging. Stay tuned for more on this tonight and Monday. See the Hazardous Weather Outlooks above.

High pressure will bring fair, but very warm to hot weather to
the area into Monday. Monday`s heat index values will range
from 95 to 100 degrees across portions of southern New Hampshire

late Monday and Monday night. Showers and thunderstorms will
accompany the front. Fair weather should return for the
remainder of the week with temperatures staying on the warm side
of normal.
SHORT TERM /MONDAY THROUGH MONDAY NIGHT/...

- 2018 - A year of decisions regarding the continuation of RichLefko.com. I need sponsors!
RichLefko.com needs two new annual sponsors to stay on the web and deliver the weather alerts you need, when you need them. E-mail alerts add up to one of the largest costs at RichLefko.com. I also need to update this website to better handle cell phones, and other portable electronics. I am willing to put in the time and effort, but I need some help to osffset the cost of e-mail, web hosting, and software.
In order to accomplish this I need two additional sponsors to add to the couple I already have. In the past I had several sponsors who have now retired their businesses.
Contact me if you, or someone you know, has a small business and would like to support the continuation of RichLefko.com. It isn't expensive. I do accept donations as well.

OWC Sales - Grad Sales - 06/15/18

Help those affected by natural disasters


Regional Weather Discussion ...


Across the nation today:

...Strong to severe thunderstorms along with heavy rain and areas of flash
flooding can be expected from parts of the Central and Northern Plains to
the Upper Midwest...

...Wet conditions for the Gulf Coast and Southwest...

...Dangerous heat and humidity will be in place this weekend over much of
the Midwest and spreading to the East Coast by early next week...

Much of the northern tier states will have several rounds of heavy showers
and strong thunderstorms as multiple waves of low pressure lift up along a
frontal zone draped across the region. Abundant moisture lifting over this
boundary will keep convection firing over this region. The Storm
Prediction has highlighted a swath from Nebraska to northern Minnesota and
Wisconsin as having a slight risk for severe weather - with an enhanced
threat today across central Minnesota. Given the expected slow progression
of this front and multiple rounds of rainfall, there will be an increased
threat for flash flooding in nearly the same locations of the expected
severe weather. WPC has a moderate excessive rainfall outlook in effect
for northern Wisconsin and the surrounding area today with a slight risk
spanning much of the Northern High Plains to Upper Mississippi Valley
through Monday. Local amounts of several inches may occur across areas of
Minnesota, Wisconsin and the Upper Peninsula of Michigan.

Hot and muggy conditions is forecast across much of the Southern and
Central Plains, as well as, the Midwest over the next few days. Afternoon
highs will generally range from the 90s to low 100s and with the high
humidity, this may increase the risk for heat exhaustion or stoke for
susceptible individuals. Some major Midwest cities to be impacted by this
include Minneapolis, MN; Chicago, IL; and St. Louis, MO. Some of this high
heat and humidity will be arriving along the Eastern Seaboard by Monday
including New England and the Mid-Atlantic.

Post-tropical cyclone Bud is rapidly weakening however moisture associated
with the system will continue to transport into the Desert Southwest.
Heavy rainfall is expected to fall across areas of southern and eastern
Arizona, southeast Utah, Colorado and New Mexico. This moisture arrival is
well ahead of the typical onset of the monsoon season, be it should be
largely beneficial as it will help to alleviate some of the ongoing
drought and wildfire concerns. Nevertheless, the rain may be heavy enough
to cause concerns for flash flooding as well. WPC has a slight risk for
excessive rainfall in effect for portions of this region.

There will be unsettled weather developing also for the Gulf Coast states
and especially areas of southeast Texas and Louisiana by Sunday and Monday
as a surge of tropical moisture in off the Gulf of Mexico and the arrival
of a trough of low pressure help to ring numerous showers and
thunderstorms to the region. Locally several inches of rain will be
possible, and this areas will need to also be monitored closely for
potential flash flooding.
