Sudden heating and increasing dew points for the past few hours have pushed us into an interesting weather pattern for the next 2-3 hours. A rather diffuse low pressure system has been over us this morning (it brought us the overnight rain). The low is now moving northeast into northern IN/MI. That’s why we’ve seen the rapid increase in winds. But, low level moisture is now dropping! Also, in the wake of the low, a cold front is now marching from west to east across southern IN and KY. The front should pass the I-65 corridor between 2 -3 P.M.
Ahead of the front scattered thunderstorms are popping up. Due to the decreasing moisture, no solid line of storms is expected. But, some isolated storm or two could generate some gusty winds, perhaps (but not likely) even up to 50 mph. Any thunderstorm threat locally will be over by 3 P.M. Stronger storms, even a severe storm or two, could pop up over eastern KY later this afternoon.
About those winds…
1). We are under a Wind Advisory this afternoon.
2). National Weather Service Definition of a Wind Advisory is sustained winds of 31-39 mph for at least an hour and/or wind gusts of 46 mph to 57 mph.
3). The current NWS forecast predicts wind gusts up to 40 mph.
4). The current Hazardous Weather Advisory and Weather Advisory say gusts to 45 mph.
5). Go figure! Why issue an Advisory for something they aren’t forecasting?
6). And, the prediction isn’t even going to happen. The strongest wind fields are over eastern KY (east of I-75). Locally, our wind gusts should top out in the mid 30’s.
