Warm weekend ahead; Showers spread northward Sunday from Delta remnants

Posted Friday, October 9, 2020

Probably the best weather in the USA will be right here today. High pressure to our southeast will bring a southerly flow today. It will be a gorgeous autumn day here in the Valley with plenty of sunshine and hard to find a cloud in the sky. Afternoon temperatures will top out in the mid-70s. Normal highs this time of the year run about 67° so we’ll be about 8° to 10° warmer than average.

FRIDAY WEATHER MAP

Our area will be between two weather systems on Saturday. A cold front will be moving our way from the northeast as the remnants of Hurricane Delta advance northward towards the lower Ohio Valley. The end result for us will be increasing cloud coverage Saturday but we’ll stay dry and warm despite the heavier clouds. As warm moist Gulf air spreads northward, it will turn noticeably humid as well.

Odds for rain showers will increase on Sunday as the leftovers from Delta travel up from the south. That approaching cold front will help to keep the highest rain amounts south of the Valley. Most of the rain locally will fall Sunday night into Monday morning.

NWS-WPC PROJECTED TOTAL RAINFALL through Tuesday evening

While Delta and a crossing cold front will bring desperately-needed rain to the area, it won’t bring much. The morning model runs show a spread of about a quarter to a half-inch is likely in our area through Tuesday evening.

RAINFALL MODEL SPREAD as of Friday morning

The cold front should be south of the region by Tuesday morning. High pressure will return dry and sunny weather conditions to the Valley. Temperatures will be cooler of course behind the front with highs closer to average (upper-60s).

A pattern change late next week will bring chilly October temperatures. Gardners will need to pay attention to next weekend. Nighttime lows may get close to freezing.
