The last full week of March- or the first full week of Spring- will behave fairly typically for this time of the year.
High pressure early in the week will bring a couple of sunny, but cool days on Monday and Tuesday. Monday should be the coldest day of the week, with temperatures only reaching the mid 20s. Highs on Tuesday will be a bit better, but still about 10º below normal in the mid 30s. Temperatures Tuesday morning will likely vary quite a bit by location, depending on geographical influences as well as some areas of cloud cover. Single digits and teens should be expected.
Warmer weather starts to move in for Wednesday and Thursday, with temperatures closer to and even above normal. Exactly how warm each of these days gets will partly depend on the track and timing of a couple of weather systems. First, a warm front will move through on Wednesday. Then, low pressure will develop to our southwest and move overhead on Thursday. Temperatures on either day could end up varying quite a bit across the region, with the warmest weather on Wednesday further west, and on Thursday, further east.
In addition to the warm temperatures, rain will be possible on Wednesday and likely on Thursday. While Wednesday’s rain may end up more showery and in the afternoon, Thursday could have a period of steady, moderate to even heavy rain. There could be some minor flooding concerns from this, but thankfully, at this time, it does not look like a major flooding threat.
Colder air will work back in by Friday, with another day of lake effect flurries and squalls, especially early and late in the day. I would not be surprised to see flurries around on Saturday morning, but the rest of the day should be sunny. Temperatures warm and rain moves back into the forecast Sunday afternoon.
