NH1 Weather Insider: Weekend No Washout...But...
NH1 Chief Meteorologist
Sunshine starts off the weekend with high pressure off the coast! Saturday will be the best outdoor day of the weekend so make sure to make the best of the good weather while you can! High pressure parked off the coast will supply enough dry air to keep the daylight hours dry across New Hampshire. Sunshine will fade to partly sunny skies, and eventually surrender to mostly cloudy skies during the afternoon. Highs will be in the Lwr-mid 70's inland, away from a light ESE wind which will keep temperatures in the 60's to near 70 at the beaches.
The nice weather this weekend is not meant for this world. A low from the midwest will track right over Ohio and then right through New England this weekend. The much talked about rain will begin to spread into New England Saturday night. Rain will quickly become heavy toward midnight with the heaviest rain falling between 12 AM-8 AM Sunday. With the low tracking into western New England, strong winds from the SE will develop ahead of this low. By dawn Sunday, peak winds from the SE with gusts up to 30 mph or greater will be possible Sunday morning, especially at the coast. The heaviest rain will start to lift out and away in the afternoon, leaving us with clouds, scattered showers and drizzle and temps in the 60's. Meanwhile, Southern New England will burst into the warm sector behind this occluded front. Highs will climb into the 70's in SNE on the warmer and drier side of this front. We will remain on the cooler, damp side right into the afternoon with highs in the lwr-mid 60's Sunday. It will be widespread soaking rainfall with about .50-1.5" of rain likely to fall. There is the potential for a few areas to see up to 2" in any very heavy slow moving downpours. So it looks like the worst of it will be while most of us are asleep Saturday night and early Sunday. A good day for sleeping in!
On Monday morning, clouds will still be in place as the upper low crosses over the region. Even a few light showers may still be in place for the early morning, especially across the north country. Drying WNW winds behind the departing low should help allow for breaks of some sun to develop by Monday afternoon with highs in the lwr-mid 70's. Tuesday will continue to warm to near 80 with SW winds ahead of an approaching cold front. A few late day showers are possible along this cold front, but most showers will hold off until Tuesday night through early Wednesday morning. Brief early morning downpour with even a thuinderstorm will be possible. Clearing skies will follow with plenty of sunshine to end the week and warming temps into the Lwr 80's.
