Strong northwest winds put a bite in the air today despite sunshine and temperatures reaching near 30 degrees this afternoon. Low pressure over the Canadian Maritimes, responsible for the gusty winds of today, will lose its grip over the region tonight as high pressure continues to build into southern New England through early Tuesday.
Our attention will turn to low pressure in the Great Lakes, which is forecast to track into southern Canada. The attendant warm front lifts through here during Tuesday with a cold front swinging across the region at night. Expect skies to rapidly cloud over Tuesday and showers may break out in the afternoon. With milder temperatures in place, highs into the 40s, by the time the precipitation arrives it is expected to be all rain. Overnight, showers wind down and may end as a period of light snow or snow showers as temperatures fall through the 30s. Perhaps a coating to possibly an inch of snow could fall, and if so the better chance would be north and west of Springfield. The rainfall amounts should generally be two-tenths to 1/3rd of an inch.
Once the cold front moves east of the region the gates are open once again for colder air and a brisk wind to overspread the area Wednesday and Thursday. Generally fair skies prevail both days as highs climb into the low 30s, but gusty winds will make it feel much cooler.
By Friday the winds ease and temperatures rebound slightly. Clouds are on the increase in advance of low pressure that will move out of the Plains States, into the Ohio Valley and towards southern New England this weekend. This system should be a player in our weather over the upcoming weekend, however many details need to be sorted out over the next few days before getting a better idea as to what the impacts from this system will be.
