NH1 Weather Insider: Cooler Thursday, Weekend Warm Up
NH1 Chief Meteorologist
Plenty of dry air remains in place Thursday with weak high pressure sitting above us with light onshore winds on Thursday. High to mid level clouds are increasing today ahead of a low riding on a stalled front south of New England by tonight. Filtered sunshine will give way to thickening cloud cover by the midday and afternoon. Highs will be cooler in the 70's. Temperatures will be warmer inland in the mid-upper 70's, and cooler at the coast near 70-73 with a light wind shifting to ESE by afternoon. We will have to watch the track of the low closely as it will come with a period of heavy rain, and maybe even an embedded thunderstorm. While the low should track along the south coast of New England, and keep the heaviest rain in southern New England, there is a potential for Southern New Hampshire to get clipped with a brief period of steady showers Thursday night towards midnight.
As the low pulls away in the early morning Friday, winds will be shifting back to the WNW wind direction and we will begin a nice summer warm up which has been a long time in the making! Skies will turn mostly sunny Friday with highs in the mid 80's. There appears to be some sort of weak front which will sag into New England this weekend. I expect plenty of sunshine and warm temperatures in the 80's, but the proximity of this front with the heating of the day could be a trigger for some cumulus development in the afternoon or even an isolated shower especially in the mountains both Saturday and Sunday. Highs on Saturday will be in the mid-upper 80's with sunny to Partly sunny skies, Highs will come close to near 90 Sunday with mostly sunny skies. It really looks like a great weekend to be at the beach or on the lake or your favorite swimming hole! It is about time. I have yet to go swimming yet!
The high pressure ridge will begin to break down on Monday but not before we squeeze in one more hot, humid day with highs in the upper 80's with partly sunny skies. There will be a chance of a late day shower or thunderstorm as the humidity increase. A slow moving low will be digging into the Great Lakes and slowly meander eastward. With a deepening trough in the Northeast, numerous showers and thunderstorms will prevail starting Tuesday and Wednesday with the potential to last into Thursday. These storms will be loaded with water with heavy downpours and the potential for some stronger storms. The trough in the Northeast will be a pattern which takes us through the 23rd, with temperatures at times running seasonally cooler. After that, we should see a return to a hotter pattern with a ridge shifting to the east coast from the 23rd to 29th of July....in case you are looking to make plans!
