A sunny, pleasant Easter Sunday followed by rain, possible thunderstorms

My apologies for the lack of posts over the last couple of days. I've been fighting off what the PA at the walk in clinic referred to as a "viral infection", though they weren't able to tell me exactly which system was infected... I had a 102.7° fever last night, which sets a record high going back to about 1985. Hoping whatever is afflicting me will be out of my system soon.

Tomorrow will be quite a pleasant day, with highs pushing the upper 60s, and abundant sunshine over SE Michigan. Expect cloudiness elsewhere, but no precipitation until the afternoon hours. The exception is the U.P., where it could rain/drizzle pretty much all day. The western and northern portions of lower Michigan may begin to see rain as early as 1PM, but the main portion shouldn't kick in for those areas until 5PM. For the rest of us, rain should hold off until around 11PM. That's when the bulk of a fairly decent storm system is going to start moving into the area.

With the sunshine and temperatures being what they're forecast to be tomorrow, we should have a bit of instability in place even into the evening hours, which may drive some thunderstorms (as can be seen above). I wouldn't be surprised if one or two of these in the SE Michigan area cross severe thresholds, as winds aloft should be quite strong, though most should only have 30-40mph gusts, per the latest models.

Expect the rain to continue in central/SE Michigan until Monday afternoon. Monday should be much cooler, with highs between 45 and 50°. Monday night we'll drop back below freezing, and Tuesday should be a repeat of Monday in terms of temperatures. We should start warming back up considerably on Wednesday, though another storm system should pay us a visit Thursday. After this, temperatures will start to go down again.

The real kicker is the clipper system that should be coming Saturday. Right now, it looks too warm for snow, and it remains to be seen just where the bulk of the precipitation will land, but the real news is what comes after. Temperatures may plummet - we're talking lows in the teens and highs in the 20s for at least a couple days. This may sound ugly, but I'd not worry too much, as temperatures will likely be on the rebound fairly quickly after that.
