Rain chances will increase over the course of the day as low pressure approaches the region. Multiple rounds of light to moderate rain are expected over the course of the weekend.
Rain associated with the pair of weather systems we discussed in yesterday’s update will advance into east-central Ohio this afternoon. At first, the rain will be a little slow to develop due to the dry atmosphere in place. Rain overhead will evaporate before reaching the surface. Eventually, though, moisture will overcome this dry air and begin.
Simulated FutureCast radar this afternoon through 5:00 AM Saturday:
For the folks heading out to the Dover/New Phila game this evening: Light rain showers and chilly temperatures will just enough of an east wind to make it feel colder. It will not be a pleasant evening for football, so dress warm and dry.
Widespread rain will continue overnight and into Saturday morning. We may get a break in pretty much steady rainfall Saturday afternoon for a short period. Showers will taper off and become hit-or-miss during the afternoon and evening.
With rain and clouds around, temperatures will struggle to reach 50 degrees for the afternoon high.
Scattered light rain showers/drizzle will continue overnight. Lows Saturday night will bottom out at around 40/42.
Low pressure associated with this first batch of rain will depart on Sunday just as system number-two approaches from the west. High-resolution guidance shows a decent break in precipitation Sunday morning into Sunday afternoon. Showers will move in from the west by mid afternoon and once again overspread the region by mid to late afternoon Sunday.
This second storm system will be quick to move through east-central Ohio. Showers will begin to become more scattered in nature by 8:00/9:00 PM. I still expect some lingering scattered showers overnight, but these will exit east and precipitation should end late Monday morning. We may even get into some spotty sunshine Monday afternoon as the clouds thin out.
The good news is that temperatures will remain warm enough through the period and snow will be unlikely here in east-central Ohio.
The models are in fairly good agreement for total precipitation through Tuesday morning. Most areas in the Valley should see an inch to 1.25 inches Friday night through Tuesday morning.
TUESDAY AND HALLOWEEN
High pressure will bring sunshine back to the region on Tuesday. And, a bit of a warming trend gets underway as well. With sunshine and fair-weather clouds dominating, temperatures will warm to the mid-50s for the afternoon high.
Temperatures will continue to warm on Halloween with highs reaching 60 degrees. Low pressure moving across the Great Lakes will drag a cold front across Ohio. With the front approaching, chances for showers will enter the forecast Tuesday night and Wednesday. There are still some timing issues between models regarding the timing of showers, but we have plenty of time yet for these to work out.
