I’m Jack Sillin, freshman at NYA, snow-lover, enjoyer of the outdoors, and of course, weather geek. My passion for weather began several years ago when I was about six years old on a series of long plane trips while watching countless hours of The Weather Channel. My skills have evolved rapidly in the past few years from excitedly refreshing the radar on the local TV weather page (I’m still guilty of that from time to time…) to waking early to analyze complex charts and graphs every day to produce a forecast. I’m hoping to pursue a career in the NWS someday. Aside from the weather, I’m a big skier and lover of all things cold and snow. I also like to do many other outdoor activities such as hiking and fishing when the snow is no longer around. I can be reached through twitter @JackSillin and via email at jack.sillin@gmail.com.

Fair Weather To Continue For The Rest Of This Week

Hello everyone!

Today’s fair weather will continue for the rest of the week as a weak cold front reinforces our already cool and dry airmass. Highs tomorrow will be pleasantly cool, ranging from the mid 60’s north to the low 70’s in interior southern areas. A few showers are possible in the far north this evening as a cold front moves through, but no widespread precipitation is expected. Mostly clear skies will continue to be the name of the game, aside from some brief cloudiness in the north tonight as that front moves through.

I’ll be off the grid through Friday so my next update will be Saturday morning. If you’re looking for forecast info more detailed than what I have here, head on over to weather.us and type in your town for a full rundown of the forecast from the next few hours to the next two weeks.

Clearer, Drier, And Cooler Today

Hello everyone!

After a one-day bout of heat and humidity, a cold front will be responsible for returning the area to seasonable conditions today. Northwesterly winds are already cooling and drying the air across the region, a trend that will continue through the rest of the day. A few leftover clouds from the front are noted on satellite imagery across southern areas this morning, while areas typically impacted by upsloping are also seeing clouds. As the day goes on, the southern clouds will clear out, but continued upsloping will be responsible for keeping overcast skies along and northwest of the mountain peaks. We’ll also have a classic upslope/downslope pattern for temperatures, which will range from the low 60’s in the north to the upper 70’s along the coast. The aforementioned northwesterly breezes will keep any sea breeze circulations at bay today, with mild temps extending all the way to the shorelines.

Midsummer Heat And Strong Thunderstorms Today

Hello everyone!

As far as summertime goes, today will feature some fairly active weather as a cold front approaches from the north. We’ll deal with oppressive heat and humidity for much of the first half of the day, before strong to potentially severe thunderstorms develop later in the afternoon. Because of the active weather, this blog entry might be a little longer than usual, but I’ll try to stick to just the info you need to know.

A warm front is crossing the area this morning, and some showers are being observed ahead of it, mostly in northeastern areas. A couple of thunderstorm cells are noted along the front this morning, crossing the NH/ME border north of Bethel as of 6:50 AM. These cells are moving towards Augusta, and will bring a brief period of heavy rain and thunder to areas between Bethel and Augusta, such as Rumford.

Behind the warm front, west-southwesterly winds will develop and strengthen this morning. Near the coast, the influence of the cool Gulf of Maine will bend these winds to a more southwesterly direction, which will offer relief from the heat for Midcoast areas especially. For the rest of the area, especially SW of a Brunswick – Lewiston – Bethel line, those WSW winds will be downsloping off the hills of Southern NH. This downsloping will help to mix very warm temps down from aloft, and will also contribute to developing patchy sunshine. The result will be temps soaring into the low-mid 90’s in the favored SW warm spots, while areas farther north and east see highs in the low to mid 80’s. Meanwhile, these winds will also be transporting very moist air in our direction, and dew points will rise accordingly. The mugginess combined with the high temperatures will result in heat indexes approaching or exceeding 100 degrees. Heat advisories have been issued as a result for southwestern areas.

This heat will help fuel thunderstorm activity once the cold front begins to approach this afternoon. Look for storms to develop in two waves, one along a pre-frontal trough, and one along the front itself. The pre-frontal storms will get going in the mountains early this afternoon, before moving southeast towards the coast. Storms along the front itself won’t arrive in the mountains until early this evening, before moving towards the coast around sundown. Storms will pose primarily a damaging wind threat in terms of severe weather, while flash flooding and frequent lightning will be dangerous with any storms, even non-severe ones.

Storms will weaken after dark, and skies will clear from north to south by tomorrow morning.

It’s a little bit of a shameless plug, I know, but if you’re interested in following along with the storms like us weather people do, the company I work for has some great (free!) tools to do just that over at our site weather.us.

Watch the clouds with satellite imagery from the newest weather satellite, launched just last year.

Watch showers and thunderstorms with the highest resolution radar imagery available.

Watch lightning activity with our lightning analysis product. If you click the map to zoom in, you can even select individual strikes for a street level map of where the strike hit as well as other information about that particular strike’s intensity. The map doesn’t auto-update, but you can easily find the latest data by pressing the white refresh button at the very top left of the map.

Warming Trend Continues Away From The Coastline Today

Hello everyone!

The warming trend begun yesterday will continue today for areas away from the coastline. Winds will have more of an onshore component today, which will keep temperatures a bit cooler. Inland, look for highs ranging through the 80’s with some low 90’s possible in the typical SW ME/NH warm spots. Along the coast, temps will initially rise into the low 70’s this morning before the sea breeze kicks in and temps fall back down into the 60’s. Skies will be mainly sunny across the area with just a few high clouds here and there. A late day pop up shower is possible in the mountains, but otherwise dry conditions will continue.

Warming Trend Begins Today

Hello everyone!

After a pleasantly cool start to the summer season, we’ll begin to see a temporary reversal of fortunes today as warm air begins moving in from the west. Look for northwesterly breezes to keep any marine circulations limited to the peninsulas of the midcoast, while the rest of the coastal plain can get in on the warmth. Highs will rise into the 80’s for all but the northern mountains, and some parts of southern NH could approach 90. Temps in the mountains will be slightly cooler, in the high 70’s. Mainly sunny skies are expected to continue through the day today.

Clouds And Showers Slow To Clear Today

Hello everyone!

Low pressure sits off to our east this morning, which typically would signal clearing skies and improving weather. However, that low has a small appendage on its western side that’s dragging its feet on its way out this morning. This appendage is located over SW NH this morning, and as a result, it will be southwestern areas that will see the greatest impacts from this feature. Clouds and showers are ongoing across much of NH this morning, and will be slow to clear out during the rest of the day today. Meanwhile to the northeast, skies have already cleared in Augusta where a beautiful early Summer day is in store.

Highs today will be a function of hours with sunshine. Those that see sun most or all of the day (NE areas) will enjoy temps in the low 70’s. Those that see only a couple sunny breaks this evening, if that (Southern NH) will see temps in the mid 60’s. Areas in between will see varying amounts of sunshine this afternoon, and thus will have temps varying accordingly, but most should come in within a few degrees of 70.

Looking ahead, a big warmup is in store beginning this weekend, culminating on Monday with highs spiking into the 90’s accompanied by oppressive humidity.

Clouds And Showers Arrive This Afternoon

Hello everyone!

Today will feature a sunny start for most of the area, which unfortunately won’t last through the rest of the day. A warm front is moving through New York this morning, and its clouds will spread across the area from west to east midday today. A few showers are also possible along this boundary as it moves through later this afternoon. Following the warm front will be a cold front, set to arrive during the overnight hours. This front will spark severe thunderstorms to our west, which will be decaying as they approach our area. The CT river valley in western NH, and the mountains of NW ME stand the best chance at seeing locally heavy rain and rumbles of thunder from these storms. A brief period of showers is about all the rest of us can expect late tonight, before clearing tomorrow morning.

Temperatures will be warm today, due to both the morning sunshine and the afternoon transport of warmer air behind the warm front. Look for temps ranging through the 70’s across most of the area, with a few 80’s in central inland areas.
