NH1 First Alert Weather: Big time heat, then humid and storms

NH1 Chief Meteorologist

Get ready for the hottest day of the year so far with high climbing into the Lwr-mid 90's by afternoon. An upper level ridge sits right over us today with sunshine, light west winds and temperatures reaching levels not yet reached this year! Temps near 90-95 will be widespread across the Granite state. Even at the beach, a land breeze will help to warm temps to near 90 ahead of any developing sea breeze in the afternoon.

The slow moving frontal boundary will stall across far Northern New Hampshire and central Maine Wednesday and will be the focus area for any scattered showers or isolated thunderstorms to develop. With the very warm temps aloft and light flow, any showers should be along or to the north of the frontal boundary. Dewpoints will also be on the rise adding to the heat during the afternoon. Wednesday night the boundary across the far north country slowly drifts south and with it will be a few showers along the boundary in Coos county most likely. Overnight temperatures will be mild with lows in the 60s.

Looking ahead, with a this slow moving front backing into New England and the building humidity, the extended forecast is focused mainly on the potential for scattered showers or thunderstorms.

The first wave looks to cross the area Thursday. Model forecasts show a marine layer possibly lingering over Ern zones...which will limit instability for these locations. However...farther West conditions are looking more favorable with some potential for stronger storms. At this time there are still model timing and instability uncertainties for the long range.

This front will be right over us Thursday. On the warmer more humid side of the front, highs will be in the 80's with the better chance of afternoon showers and storms. On the cooler side of the front in eastern NH, a marine airmass will help to keep the air cooler and more stable. With the increased dewpoints, there will be a threat of locally heavy rainfall along this boundary. Both Thursday and Friday will have the chances for scattered showers and storms in the vicinity of this stalled front.

Another chance of showers will be in place on Saturday as a strong shortwave moves thru the Great Lakes and through New England which will keep the chance of showers and thunder in the forecast. Temperatures will be cooler by the weekend with highs in the 70's and Lwr 80's. Drier NW winds with lower humidity will follow back in Sunday-Monday behind the departing Saturday Low...temps will quickly warm back into Lwr-mid 80's for start of next week.
