NH1 Weather Insider with Joe Joyce: September 10, 2015

The heat wave is over, but the changes continue! The cold front is stalled off the coast this morning. Winds are shifting to the NE. Clouds will hang tough close to this stalled front. High temperatures will be cooler on the western side of the front mostly in the 70's under the clouds. This will come as welcome relief to those who can't stand the heat, but we will still have some humidity to squeeze out. We will be tracking a wave of low pressure riding up along this stalled front which will start to direct a few late day showers into New Hampshire. In fact, a few of these showers will start to become heavier before the day is through. The main batch of rain will be arriving later on Thursday night towards midnight and the overnight hours through dawn on Friday as a low tracks near Cape Cod and eventually into the Gulf of Maine Friday. Some of these showers will come with some heavy downpours with the potential of 1-2" of rain to fall by Friday morning.
Even though Friday will start off wet in the morning as we head to work and school, the low will continue to pull away and drier air continue to slide in from the north. Abundant cloud cover will be in place for much of the day, but a few breaks of sun may try to start to appear inland Friday before the day is through. Most with have temps ranging from 70-75, but some area who break into sun Friday inland could see highs in mid 70's. Weak high pressure arrives Saturday with highs in the 70's near 80 and sunny to partly sunny skies. Another weak low will approach late Saturday night which could bring in another round of showers for much of Sunday morning. With onshore winds and cloudy, damp conditions...highs will struggle to get much above 70.
Once this low pull away, upper level ridging will replace the trough in the Northeast and we will see sunshine returning through the midweek and temperatures moderating back to near 80. Will we hit 90 again? Maybe. There is still warm air in the pattern, but as each day goes by this time of year...the chances become less and less. If I was a betting man, I think we have another day or two in us...before it is all over...but a heat wave like we just saw is very unlikely this time of year!
