The weekend has arrived and so have clouds and a few light showers to start your Saturday. We have a low pressure system centered in southern Quebec this morning. It will swing a strong cold front through here this evening. Ahead of the front gusty southwest winds deliver above normal temperatures this afternoon with showers becoming more isolated after this morning. Periods of sunshine will develop later in the morning through the afternoon hours. Once the cold front passes temperatures fall below normal once again for Sunday, more so on Monday and continuing into Tuesday.
Strong Canadian high pressure will be the dominant feature Sunday into Tuesday. With a developing low pressure system across the south over the weekend, becoming centered near the North Carolina coast by Monday morning, one would think we have a good set up for a winter storm early in the week. However, high pressure will shunt the storm far enough south so that it moves out to sea and is not expected to impact the local area on Monday. The down side of this set up will be the below normal cold that will be entrenched over the region early next week. Monday will run close to 15 degrees below normal for mid March and that is still a significantly cold day for this time of year. Highs for the day will be more in line with our average overnight lows for mid March. Temperatures expected in the teens Sunday night, Monday night and more sparsely Tuesday night keep that furnace working overtime as Old Man Winter just won’t let go!
Temperatures recover back to around seasonal later in the week as another disturbance and frontal boundary brings clouds and the chance of showers by Wednesday night and Thursday. If a secondary coastal low develops then things could get more interesting on Thursday.
