This Week’s Hazards

Five-Day Outlook

Normal High: 49 deg

Normal Low: 31 deg

Five-Day Weather Forecast 

Saturday: Partly to mostly cloudy with a chance for showers, especially after 3:00 pm. Rain chances increase further after sunset.

Sunday: Mostly cloudy, with a chance for mainly morning showers.

Monday: Mostly sunny and mild.

Tuesday: Partly to mostly sunny. Clouds increase late in the day. Windy, with gusts to 20 mph.

Wednesday: Rain likely.

Forecast Discussion & Concerns 

Rain chances begin rising again by this afternoon, with rain showers being rather numerous on the plateau by sunset. Total rainfall amounts with this system should stay around one half inch.

By next week, a strong cold front will blow through on Wednesday with heavy rainfall. That front will usher in much colder air that may even lead to some snow flurries before the week is finished.

The Storm Prediction Center outlook for severe weather shows severe storms possible on Wednesday associated with that frontal passage across the South, but they currently keep the greatest threat well south of our area. Based on the current forecast data, that certainly seems reasonable. I’ll monitor that closely in the coming days.

HRRR Radar Model

This model begins at noon and ends at 6:00 pm, in one-hour increments. This particular model shows rain moving onto the plateau around 3:00 p.m. and increasing in coverage thereafter.
