This afternoon we're looking at highs only in the 50s to low 60s as a high pressure ridge parks itself over the region. That ridge is going to squeeze out any rain chances and keep things dry through most of Tuesday. Tonight into Tuesday morning, though, watch out for frost. Clear skies, calm winds, and low humidity are going to let temperatures radiate right back down to the low and mid 30s inland from Lake Erie, so frost is pretty much a lock across much of northern Ohio and northwestern Pennsylvania.
Here's what makes this setup interesting: that high pressure ridge is going to shift eastward on Tuesday, and when it does, warm moist air is going to start flowing up from the Gulf of Mexico. At the same time, an upper-level trough (that's a dip in the jet stream, that river of fast air around 30,000 feet) is going to approach from the Upper Midwest. That combination creates the perfect recipe for trouble. We'll see a warm front slide northeast across the area Tuesday night, followed by a cold front Wednesday into Wednesday night. All that lifting and wringing of moisture will produce periods of rain and occasional thunderstorms Tuesday evening through Wednesday. The rain could be steady to heavy at times as that Gulf moisture collides with the cold front.
After the system clears out, lake-effect rain will linger through early Thursday, especially downwind of Lake Erie. By Friday, we're done with the wet stretch and we transition into a warming trend that'll push us from the 60s Friday up into the 80s by Monday. That's a typical late-spring pattern where warm air returns on the western flank of high pressure moving east, though scattered afternoon storms are possible as Gulf moisture gets re-established.
Quiet and cool this afternoon with highs only in the 50s to low 60s. Clouds increase tonight ahead of Tuesday's system.
Tomorrow
Clouds thicken and a few sprinkles are possible by evening. Frost or freeze conditions likely again overnight into Tuesday morning with lows dropping to the low-to-mid 30s inland.
Frost Advisory or Freeze Warning likely for most of the area tonight into Tuesday morning, with inland lows dropping to the low-to-mid 30s. Cover sensitive plants.
Tonight into Tue morning
A warm front sweeps through Tuesday night, then a cold front Wednesday, bringing periods of rain and occasional thunderstorms through Wednesday evening.
