Another possible busy week (March 19-25) is ahead with the chance for one or two more nor’easters that could bring snow to our area. The uncertainty remains very high, however. What I do know is that the first day of spring is on Tuesday, and it will remain chilly this entire week.
Monday, Mar. 19: Monday will be a beautiful day to begin the new week, featuring mostly sunny skies, pretty light winds, and a high temperatures in the low 40s. Despite the higher-sun angle on this final day of winter, the upper-level air pattern will prevent the temperatures from getting any warmer.
Tuesday, Mar. 20: Tuesday will be the first day of spring but it sure won’t feel like it and it may not look like it either. That’s dependent on whether we get impacted by another coastal storm. The model guidance has been struggling greatly the past several days on if we will deal with another storm. The recent runs of these models keep this storm just far enough to our south for minimal impacts. It seems as though we’re going to get brushed by the northern extent of its precipitation shield, so that would lead to a light snow beginning some time Tuesday afternoon and continuing through the evening. I don’t think this will be a big snow event, if we do receive any snow at all, based on the warmer ground, the higher sun angle, and the light snowfall rates this storm will deliver. Monitor the forecast from Jackson’s Weather for the latest developments.
Wednesday, Mar. 21: On Wednesday, as the first coastal storm heads out to sea, believe it or not, another coastal storm will develop, and this one will be a nor’easter, the fourth so far this month. The graphic that I made below shows the satellite imagery of the past three nor’easters from this month. Is a fourth on the way?

This storm will be stronger and has the potential to rapidly-intensify off the Carolina coast beginning Tuesday night. Depending on the position and the timing of a trough which is steering this low pressure, it could end up pulling this storm closer to the coast. At this time, this storm is expected to track out to sea, but will have a but more of a south to northerly orientation to its track due to the trough. This means that it will impact the Canadian Maritimes instead of zooming toward the east and into the central Atlantic. With many coastal storms this winter, the models have often featured a last minute correction to the northwest where all of a sudden it appears that New England will be impacted by the storm. Could this happen with this week’s storm? It’s quite possible. Therefore, I do have snow in the forecast for most of the day Wednesday, and there is the potential for accumulating snow. We just don’t know at this time, so stay tuned.

Thursday, Mar. 22: On Thursday, our coastal storm should clear out either way. You can expect partly cloudy skies and high temperatures in the mid 40s.
Friday, Mar. 23: By Friday, this active storm pattern responsible for producing all of these nor’easters will likely break down, but that doesn’t mean the cold won’t go away. Friday should be a pretty nice day, featuring intervals of sun and clouds with a high temperatures in the mid 40s.
Saturday, Mar. 24: Saturday will also be a nice day to kick off the weekend. Expect mostly sunny skies paired with a high temperature at average, which is the upper 40s.

Sunday, Mar. 25: Unfortunately, a new storm system is expected to begin moving through on Sunday. This storm will bring rain and/or snow, which is dependent on the track of the low pressure arriving from the west as well as the temperatures. It’s still too early to know what precipitation type we will deal with at this time.
