Low pressure will track well to our west into southern Canada as mild air advances northward ahead of this system tonight. Before the milder air gets here we stay cool with a threat for some freezing drizzle and or rain early tonight, then as temperatures actually climb later tonight any freezing rain threat will be gone as we transition to all rain. Before that happens there could be a few hours of slippery travel during this evening and early tonight. The National Weather Service has a Freezing Rain Advisory in effect for the greater Springfield area until midnight.
Periods of showers continue after midnight into Monday morning. A few embedded downpours are possible during the morning ahead of an advancing arctic cold front. This front will cross through the Pioneer Valley during the day and then it begins to turn colder. The showers taper off during the afternoon but may end as a period of snow showers or flurries late day into the evening.
Skies partially clear out Monday night as it turns bitterly cold once again. Gusty winds will drop those wind chills to 5 to 10 below zero.
Don’t expect the thermometer to move much, if any, on Tuesday. Arctic air will continue to be fed into the area on strong winds and temperatures will not move but a couple degrees from the morning lows. We then dip to around zero overnight.
With high pressure in control we can expect fair skies Wednesday and early Thursday. Temperatures do moderate slightly on Wednesday and more so Thursday.
Unsettled weather may arrive Thursday night into Friday in the form of light snow or snow showers. It does not look to be a big deal at this point.
