NH1 First Alert Weather: Few Storms Before The Weekend
NH1 Chief Meteorologist
After a brief fall Thursday, dew points have increased overnight into the 50s. A more humid feel will be in place this Friday with dew points climbing into the 60's by the afternoon. Friday will start off sunny with southerly flow developing ahead of an approaching low. A short wave and surface low will dive southwards out of Canada on Friday pushing another cold front through the region. High dew points will again move in ahead of the front making for a sticky afternoon. Moderate instability ahead of the front may result in thunderstorms...especially in the CT river valley where the front will arrive closer to maximum heating. While the winds speeds aloft are sufficient for severe thunderstorms... the cloud cover may limit surface heating so any severe threat should be isolated. Highs on Friday will be climbing to near 80-86 during the afternoon.
A moisture rich environment in place Friday night ahead of the approaching cold front will again mean efficient rain production which along with very slow storm motion will provide an isolated flooding threat. The window for stronger storms and downpours will be Friday night as the front is pushing through between the windows of 8 PM and 2 AM.
Cold frontal boundary will be moving east of the region and off the coast Saturday morning bringing an end to any organized shower and t'storm activity. Lingering cool cyclonic flow aloft may allow clouds to build during the afternoon and an isolated shower in the mountains during the remainder of the day. Cooler than normal nights are expected this weekend with the cooler dry air in place. More sunshine, fair weather and gradually warmer weather is then expected Sunday through Tuesday. Thereafter it`s possible that high heat and humidity will build middle-end of next week with highs in the upper 80's nearing 90+.
