Extremely Hot and Humid Today

Hello everyone!

Today will feature extreme (for our region anyway) heat and humidity as southwesterly winds pick up ahead of a cold front approaching the region from the west.

Satellite imagery this morning shows mostly sunny skies across southern parts of the region while clouds drift through northern parts of the area. These clouds are the remnants of thunderstorms that developed last night over Quebec. A few of those clouds are still producing a few raindrops near Greenville. These should dry up over the next few hours.

Generally dry conditions will prevail until late this afternoon/evening when a couple showers could pop up over the higher terrain.

The main story today will be the heat and humidity. Partly to mostly sunny skies and incredibly warm air aloft will allow temps to soar to near record levels especially across southern NH and southwestern ME.

This map shows NWS forecast high temperatures for the Northeast today. Circled stations are those that may break today’s record highs. Temps in the upper 90s will do just that in southern NH this afternoon. Most of the central NH and interior SW ME will be a touch cooler (low/mid 90s). The mountains and northern parts of the region will benefit from a few clouds this morning and will only see highs in the upper 80s. The best place to be this afternoon will be along the Midcoast where onshore south-southwesterly winds will kick up late morning and bring a relatively cooler marine airmass onshore (highs in the upper 70s to low 80s).

One other note about today: it will be quite humid, even (especially) where the hottest temperatures will be found. As a result, heat index values will surge above 100F over southern NH and adjacent parts of SW ME.

Other spots away from the immediate shoreline will see heat index values in the mid/upper 90s. The NWS has issued a heat advisory for most of the area outside the mountains and Midcoast due to these high heat index values. If you can, limit the amount of time you spend outside during the heat of the day. If you do need to be outside, make sure to stay hydrated and take frequent breaks!

It will be anothah scoahchah tomorrow though with the added excitement of a few showers and storms.
