Summary - The week ahead -
...Mostly cloudy with highs in the upper 70's today. Maybe a shower in the afternoon. Skies become partly cloudy on Sunday, with highs soaring into the upper 80's. The heat is on for Monday with temperatures reaching the lower 90's. Showers and thunderstorms will affect the region each afternoon Monday through Thursday. Temperatures will moderate throughout the week, down to the upper 70's for Friday.

Near term - through 9pm this evening -
...Short wave will be moving through today. A band of mid level clouds extended across northern MA and southern NH this morning. Clouds will break up somewhat towards the late morning for a period of partly cloudy skies through the early afternoon. Clouds increase this afternoon out ahead of the short wave. There will be a slight chance of a shower through the late evening, however precipitation will be confined mainly to the north.

Temperatures started out in the upper 50's to 60's across the region. 850mb temperatures around 15C will not reach full potential at the surface due to cloud cover. Expect highs in the upper 70's to around 80 today.

Short term - Tonight through Sunday night -
...Clouds break up tonight for partly cloudy skies. Temperatures will fall into the mid 50's. A warm front will approach the region on Sunday. Mid level warming out ahead will push highs into the upper 80's in Keene to the 90's across SNE. Despite frontal passage, the atmosphere will likely remained capped with the mid level warmth through the afternoon. A few thunderstorms, some strong may affect areas further north. Otherwise, partly cloudy skies will be the rule across New England. Low temperatures will fall back into the 60's Sunday Night.

Long term - Monday through Friday 7/13 -
...Record heat is possibility on Monday, with heat wave possible in parts of SNE through Wednesday. Still questionable how hot it will get. Euro insists on +24C 805mb temps, but GFS staying at 20C. Euro has had a warm bias for the past few months now, so do not trust the 24C at all. Staying closer to the GFS with 20 - 21C temps. This is still enough to boost surface highs into the low to mid 90's. Humidity will not be as high as with the last heat wave, but enough to put heat indices into the upper 90's again, with 105 possibly in Boston, Worcester, Hartford.

Severe thunderstorm potential exists each afternoon Monday through Thursday. The main day will be Thursday as cold front passes with strong wind field. Details will be posted later this afternoon in the severe weather outlook page.

Friday will be cooler, dier, with partly cloudy skies.
