Friday, May 25, 2012: Big Heat Builds In For Memorial Day Weekend

Good Friday morning, folks!

"Big heat" is returning for the first time since September, just in time for the unofficial start to summer.  We're on the road to the upper 80s today, within a degree or two of 90° on Saturday, and solidly into the lower 90s on Sunday.

Most areas will remain dry into Monday.  With that said, there is a weak cold front that's running out of gas to our north today.  This may be just enough to spark an isolated thunderstorm or two, late this afternoon and early this evening, near and especially to the north of I-64.  Take a look at the GFS forecast for precip between 5 PM and 8 PM this evening.  Coverage is overdone, but this does serve as an indication of the areas most likely to see an isolated, pop-up thunderstorm.

Most of the area will also be dry through Saturday and Sunday.  The only exception is in eastern Kentucky, where a stray late-day thunderstorm could fire over the mountains on Saturday afternoon.  By Sunday, the ridge of high pressure will be almost directly overhead, eliminating any convection, region-wide.

The weather headline remains the heat.  Sunday will be the hottest of the stretch, with low 90s rivaling records in many areas.  Lexington's record high for May 27th is 93° from 1911, and we'll be very close on Sunday.

Enjoy the holiday weekend.  Hopefully you can get to the pool or lake at some point.  Be careful not to over-do it this weekend, as the first round of midsummer heat is often hard on the body.  Heat indices will be well in the mid to upper 90s, especially on Sunday afternoon.
