This Week’s Hazards

A very wet commute is likely Wednesday morning. Be safe on area roads, especially where there is standing water.

Five-Day Outlook

Normal High: 48 deg

Normal Low: 31 deg

Five-Day Weather Forecast 

Monday: Gradually becoming partly to mostly sunny. Mild.

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

Wednesday: Rain likely, some of which could be heavy. Possible thunder. Windy, with gusts to 20 mph.

Thursday: Chance of mainly morning showers, then mostly cloudy.

Friday: Mostly cloudy, with a chance for snow flurries.

Forecast Discussion & Concerns 

A strong cold front will blow through on Wednesday with more rainfall (2-3 inches). That front will usher in much colder air that may even lead to some snow flurries by Friday.

The greatest risk for severe weather with that front is expected to stay well south of the plateau. Our threat will be heavy rainfall that could lead to localized flooding.

Forecast 5-Day Rainfall Totals

The risk for heavy rainfall is highlighted below for Wednesday. I’ll monitor that threat for our area.
