Hot, sultry conditions will be with us this morning; this will prime up our atmosphere for storm chances arriving throughout the day, as a cold front plows southeast over the area. After the front passes tonight, moisture will be shunted off to our southeast, with much cooler, drier air filtering in.
Cold Front on the Way
A cold front is working in from the northwest, with storms (what’s known as an MCS) already firing up across southern Illinois/Indiana, flirting with Kentucky counties along the Ohio River.
This has thrown a ‘cog in the wheel’ in regards to forecasting. No longer are we looking for the fresh development of cells as the front moves through, but rather a regeneration of activity as the atmosphere recovers as we get closer to the afternoon and evening.
Provided above is the HRRR simulated radar activity for this today. We could see strong to even marginally severe storm chances arriving by early/mid afternoon. The SPC has us in a 1/5 on the severe weather risk scale:
With that being said, this particular model is having the storms lose intensity before re-firing at/south of the Tennessee line. If this pans out…
Much cooler, drier air will takeover during the early days of the new work week, as high pressure located to our north puts its clockwise flow to good use, keeping winds out of the north and northeast.
Temps will be limited to the low & mid 80s both Monday & Tuesday, with dewpoints slipping down into the 50s.
Enjoy it while you can, as another surge of the summer sultry heat will be on the docket come midweek. This will once again prime our atmosphere for more rain chances Friday into the weekend.
That’ll wrap up your Sunday morning forecast. Have a phenomenal Sunday, and don’t forget to perform a rain dance or two ;). For the latest real-time weather info, see @wxornotBG.
