Tropical Moisture Arrives Today With Clouds And Showers

Hello everyone!

Tropical moisture is on the way for today as S/SW winds bring an airmass straight from the Gulf of Mexico right into our neck of the woods. The leading edge of this airmass is marked by a round of showers and storms currently over Southern New Hampshire moving into far SW Maine. Behind this batch of showers, dew points are in the upper 60’s to low 70’s. Precipitable water values (PWATs) are in excess of 2″. All this to say, there’s a lot of water in the sky just waiting to fall down.

Sadly, most of the falling down will be done from Friday through Sunday and we have clouds and only light/moderate showers today and a scorcher tomorrow before we can begin to start putting a dent in the drought.

Satellite and radar this morning clearly show the band of showers that will impact Southern NH and Southern/coastal ME this morning. Also to note is the little batch of sunny skies over far Northern areas. This will allow for marginal destabilization of the atmosphere by this afternoon. As a cold front drifts in our direction, expect some widely scattered showers and storms to pop up this afternoon/evening. While it doesn’t look like the atmosphere will become unstable enough for severe storms up there, one or two strong wind gusts cannot be ruled out.

Highs today will rise into the low to mid 80’s for most with a few upper 70’s along the midcoast.

I’ll have more on this weekend’s rain threat in this evening’s blog post.
