May 6: Beautiful Weekend, Daily Links

WEATHER

Today is “transition day” across the Midstate — as in, the transition from cool-and-breezy weather yesterday to warm-and-pleasant weather this weekend.  The Omega block (which I discussed in yesterday’s blog post) that has dominated the weather nationwide is finally beginning to shift, and that eastward shift will allow warmer weather to make its way into the Midstate:

Temperatures started off in the 40s areawide today, but most of us will warm up to the low to mid 70s by this afternoon:

Lots of sunshine today, and lots of sunshine on the way Saturday as well — a pleasantly cool start on Saturday will give way to a pleasantly warm afternoon:
SATURDAY LIVES SATURDAY HIGHS

Sunday will be just as warm, despite an increase in cloud cover and a very slight shower or storm chance Sunday afternoon.  If you have outdoor plans on Mother’s Day, I wouldn’t bother adjusting those plans around our 20% rain chance:

The forecast does become more unsettled next week, with scattered showers and thunderstorms possible from Monday night through at least Thursday.  The greatest threat of severe thunderstorms will take shape to our west, but we’ll still have to keep an eye on things around here (it IS May, after all).  Right now it looks like Tuesday afternoon should bring the highest severe potential to our neighborhood, but it’s too soon to be worried about it.
