Stuff to make using the site easier ..

I use abbreviations for many things:
PB = Peterborough
KE = Keene NH
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. On weekends by 9AM.
Make sure your browser is set to allow "pop-ups" from this site. I use them extensively and there is no danger of any viruses or anything like that.

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. If you'd like to be a part of that mailing, send your e-mail address to: Mail List

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:

9/18 -  6:21 PM:  Clear and cold tonight with some frost and freeze advisories as Canadian high pressure is centered over the region. Tonight there will be no wind, and with that high overhead, that will set us up for perfect radiational cooling and patchy frost in areas west and north of Nashua. Sunny and a few degrees warmer on Thursday with highs in the upper 60s to around 70° after that cold start. In the 40s Thursday night then temps jump a good 10° for Friday with highs in the mid 70s to 80°. The weekend looks sunny and warm, more on that in the every Thursday evening e-mail blast. Sign up below. Humberto is heading east and will clip Bermuda on the way out. Another tropical storm, Jerry, has formed in the Leeward Islands. Stay tuned.
500 visitors away from 200,000. Will it be you?

SYNOPSIS...NH/ME
Cool high pressure centers over the forecast area tonight and
will allow for a frost in many areas overnight. Increasingly
warm temperatures are expected to arrive by the end of the week
and remain for the weekend, most likely well above normal. A
cold front will approach on Monday and Tuesday with a chance of
showers as it moves through.

SYNOPSIS...MA
High pressure builds over New England tonight and lingers over
the region through early next week. Below-normal temperatures
late this week will trend to above-normal temperatures over the
weekend and early next week. A cold front brings the next chance
of showers early next week. Distant Hurricane Humberto will
bring high surf and dangerous rip currents late this week, which
should peak on Friday.

LONG TERM /FRIDAY THROUGH WEDNESDAY/...

Highlights...

* High surf and building seas from Humberto on coastal waters
Friday, highest east. Subsiding trend late Friday.

* Dry pattern through the weekend with above- to significantly above
normal temperatures.

* Cold front early next week offers next chances for rain.

9/18 -  6:31 AM:  High pressure will move directly overhead today bringing us a cool, but sunny day. Tonight there will be no wind, and with that high overhead, that will set us up for perfect radiational cooling. Patchy frost will form and a frost Advisory is posted for Cheshire county NH. Further north, a freeze advisory is up. Check back for the evening update to see if this frost advisory is expanded. We begin a warming period on Thursday as this high pressure cell over the region slowly shifts east and the return flow around the high brings warmer air north from the SE. High temps will be around 70 on Thursday, in the mid and upper 70s on Friday and even warmer weather is expected for the weekend. Humberto is heading east and will clip Bermuda on the way out. Another tropical depression has formed in the Leeward Islands. Stay tuned.
500 visitors away from 200,000. Will it be you?

SYNOPSIS...NH/ME
Cool high pressure builds across the forecast area today and
tonight and will allow for a frost in many areas overnight.
Increasingly warm temperatures are expected to arrive by the end
of the week and for the weekend, most likely well above normal.
A cold front will approach for Monday and Tuesday with a chance
of showers as it moves through.

Sunny and a bit warmer with high pressure right overhead for
Thursday. Postcard perfect in all likelihood.

SYNOPSIS...MA
High pressure will maintain an extended period of dry weather
into this weekend other than perhaps a brief spot
showers/sprinkles this morning. Below normal temperatures into
Thursday will moderate by Friday with unseasonably warm
afternoons this weekend into Monday. Distant Hurricane Humberto
will bring high surf and dangerous rip currents late this week,
which should peak on Friday. A cold front may finally bring a
few brief showers sometime Monday and/or Monday night, but if
any rain occurs amounts will be light.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...

*/ Highlights...

- High surf and dangerous rip current conditions along ocean beaches
- This the result of ocean swell associated with Cat 3 Humberto

- Mild days, cool nights through the week, dry throughout
- Weekend heat prior to an early week cold front with spot showers
- Warmth building back over the following week

Regional Weather Discussion ...

Manchester NH —

The quiet weather stretch looks to continue for the remainder of the week into the weekend with temperature changes taking all the headlines. After some cooler air in the short term, there will be a surge of summer warmth that starts late in the week and goes through the weekend.

Today will be sunny but cooler with highs only in the low to mid 60s with a northeasterly breeze, feeling like autumn.

After a frosty start in places Thursday, hard freeze possible up north, it will be sunny and milder with temps returning close to normal for this time of year: 68-73° from north to south, but cooler mid 60s at the coastline.

Temps climb even higher on Friday, with 70s for most and then 80s through the weekend into the first day of fall on Monday. The next chance of a few showers will come late Monday or Monday night.

These "discussions" are from the NWS, or WMUR Manchester NH, or me.
