Ugh! What a humid start to the day. A cold front is pushing through Wednesday morning. This front will trigger a few morning showers as it pushes through New Hampshire. It will take until lunchtime to finally pull off the coast. The best window for showers will be between 7 until 10 AM, although a few showers could pop up at the coast around 10 am to Noon. Severe storms will be possible in Southern New England during the afternoon. Either way, as the front pushes off the coast, drier, less humid air will settle in across New Hampshire slowly during the afternoon with skies turning partly to mostly sunny. Lwr-mid 80's will reign across SNE and towards the seacoast. Meanwhile in the lakes and valleys, temps should remain in the 70's.
High pressure slides in Wednesday night with clear skies and a more comfortable night for sleeping with lows in the 50's. Winds will shift to the NE to keep it cooler at the coast Thursday with partly sunny skies. Thursday will start off with sun and clouds, but clouds will be increasing during the afternoon as a wave of low pressure rides along a front stalled south of New England. Most showers will be light and likely be directed into Southern New England...but it is possible of a late day shower across Southern New Hampshire later Thursday. With a light cool onshore wind, and increasing clouds...temps will mostly remain in the 70's during the afternoon.
High pressure follows in behind with warmer temps on a WNW wind flow with sunshine Friday and Saturday and temperatures warming into the mid 80's. Saturday may flirt with a few upper 80's in spots. Humidity levels will remain at moderate levels with the increasing warmth through this time. Sunday will be another very warm day with temperatures climbing into the 80's nearing 90. A strong vortmax (Low pressure) will dig in from the Great Lakes. Scattered t'storms may develop later in the afternoon along a warm front. This energy will drive the upper level winds south in the form of a developing trough in the northeast which will create a set up for showers and storms to generate around a slow moving low pressure center which could take until Tuesday to finally push through. Late Sunday through Tuesday expect scattered showers and storms. Some rain will be heavy, and there will be the potential for some severe weather.
Looking down the road, there will be several other chances of showers and thunderstorms coming our way during the rest of July. It will keep the meteorologists busy, and our eyes paying attention to the weather as there will be quick changes. For now, my eyes are for the upcoming weekend warmth! Finally, a weekend where it will really feel like summer. It only took us to July 11th!
