After experiencing very comfortable and beautiful weather the past few days, the humid airmass once again arrives in time for the work week. With it brings the chance of showers and thunderstorms Monday and Tuesday. Dew points will soar into the upper 60s and between 1000-2000 surface base CAPE values are forecasted per models both days. These values increase the potential for development of severe weather. Tuesday looks to be more conducive for severe weather than Monday as instability increases in response to a cold front passing through. At this point, the rain does not look like to be widespread which is unfortunate because we do need the rain badly here. The most recent U.S. Drought Monitor graphic confirms that Western Massachusetts is under a moderate drought (see graphic). Generally, expect afternoon and evening thunderstorms both days with an increased coverage of thunderstorms on Tuesday. Highs will be in the upper 80s to lower 90s with heat indices making it feel near mid 90s at times. Best chance of a pop-up thunderstorm on Monday is in the western portions of the region while on Tuesday, the best chance is east. A reminder... any thunderstorms have the potential to produce heavy rain in a short period of time. Also, be wise and get indoors if you hear thunder. Heed the warnings if a Severe Thunderstorm Warning is issued for your area. Once the cold front kicks away the muggy airmass, we are awarded with two days of splendid, sunny, summer weather on Wednesday and Thursday. Both days feature less humidity, sunny skies, and highs in the lower to mid 80s. After Thursday, things become uncertain. There could be another front working its way here bringing another round of showers and thunderstorms or the nice weather continues into next weekend. Time will tell. That's it folks...enjoy the upcoming week and make sure to keep it locked here and follow my Twitter for the very latest on the severe weather potential!
