NH1 First Alert Weather: Heat and humidity awaits NH after gorgeous Wednesday
NH1 Chief Meteorologist
High pressure will slide off the coast south of New England on Wednesday. Should see a mix of sun and clouds in the mountains and sunny skies elsewhere. Highs will range from the mid 70s north to the mid 80s in the far south. Just an amazing outdoor day all around! Fair conditions will continue Wednesday night as high pressure remains parked south of New England. Should see a slightly warmer night as return flow brings somewhat warmer air back into the region. Lows will range from the upper 40s to lower 50s north and in the 50s to near 60 south.
Thursday looks like it will be a warmer day with dewpoints rising a tad into the mid to upper 50s. Fairly comfortable with the sunshine and highs climbing into the 80's nearing 90-92 in spots by afternoon. As a warm front be approaches Thursday night, Dewpoints will rise into the mid 60s by Friday morning as the warm front lifts north.
Friday will be hot and humid with temps soaring into the lower 90s again for southern NH. Dewpoint temperatures will be close to 70 with a more tropical feel. Heat index values will feel closer to the Lwr-mid 90's by afternoon. Showers and thunderstorms will develop during the day. Some of these may become severe. Scatterered Showers and thunderstorms will continue into the evening. The cold front will pass offshore Saturday morning. However the air mass will not change much as Saturday will still see high temperatures in the mid-upper 80s to near 90 in southern New Hampshire. Dewpoints should drop into the lower 60s. A secondary cold front will move through Saturday afternoon with a slight chance of an afternoon shower and thunderstorm across the north country. High pressure will build in for Saturday night and Sunday.
After slightly cooler arriving for Saturday, Heat and humidity will rise again on Sunday with highs in the Lwr 90's. This hot and Humid airmass will take us right into Monday. A front will approach for the afternoon which could trigger scattered more afternoon showers or t'storms Monday. More comfortable air will be in place for next Tuesday-Thursday.
