Friday 9/21 Forecast Discussion: More Rain and Cold Coming

We had a nice day yesterday, but unfortunately that nice weather is about to come to a screeching halt. Welcome to your Friday morning forecast for September 21, 2012!

TODAY: We’re going to start off dry, and warmer than the last two mornings. We’re back in the upper 50’s to low 60’s as I type this before 4:00 AM. Now, the clouds have on the increase and that will continue to be the case. By the afternoon we stand a chance of showers with maybe a rumble of thunder. This is the first of two disturbances to push through here in the next 48 hours, rounding the base of an upper trough and bringing a surface low through the area tonight. Highs today will be around 71 because of the cloud cover.

TONIGHT/SATURDAY: Rain chances will be pretty good through tonight, and even the first part of tomorrow. We’ll drop back to around 57. It’s pretty clear to me that Saturday morning at least will be wet from the first disturbance, and skies will remain mostly cloudy. The second storm, a cold front out of the upper midwest, will drop down and through late day and with that I still cannot rule out some rain, but it will be primarily north of the Ohio River. Highs will be around 70.

SATURDAY NIGHT-MONDAY NIGHT: Get ready for some more cold weather, but it’ll be dry through this period. Saturday night lows drop into the middle 40’s on a northwest wind. That’s not even the coldest air. Sunday highs will recover only to around 62. That clears the way for the bottom to fall out on Sunday night. By Monday morning, most everyone should be between 37 (coldest rural areas) and 43 (in the city). As we go through Monday and Monday night we’ll be on the backside of high pressure which should allow for southerly winds and a warming trend. Highs will be around 67 on Monday afternoon with lows Monday night around 45.

TUESDAY-WEDNESDAY: We’ll keep the warming trend going, with highs of 75 Tuesday and 77 Wednesday, and lows around 54 on Tuesday night. Again, that south wind should help quite a bit.

WEDNESDAY NIGHT/THURSDAY: Our next little wave of low pressure will move in on Wednesday evening, and the models show that a front kind of drapes itself across the Ohio Valley region. The front itself won’t be the troublemaker, it’ll be the little impulses that ride along the front. I have to add in a rain chance — but we’ll keep it at 30 percent right now. It still looks as though highs stay in the 70’s on Thursday after lows in the 50’s Wednesday night.

SOCIAL MEDIA: Follow along with me as I watch the next rain threat:
