Friday Forecast (11/17/17)

Today – Partly Cloudy – High 61° / Tonight – Windy & Cloudy – Low 58°

High pressure has moved to the east of the region today. This will put us in a southeasterly surface flow, which should help temperatures rebound to around 61° by late afternoon.

This will also keep overnight temperatures mild. Lows will only drop a couple degrees before warming through most of the night.

Saturday – Storms Possible – High 64° / Sat Night – Partly Cloudy – Low 32°

The aforementioned low pressure system will push a strong cold front into the region on Saturday. This will bring a chance of storms, some of which could be strong to severe. The Storm Prediction Center has placed our region in a “marginal” risk of severe weather. Think of this as a level 1 out of 5.

Damaging wind will be the main severe hazard. Wind gusts outside of storms could cause some damage as well. Southerly winds will continue to gust in excess of 40 mph ahead of the front.

A sharp nosedive in temperatures are expected after the cold front passage. Temperatures could drop some 20° in just an hour or two. Meaning we could go from mid 60s around noon, to the mid 40s by early afternoon!

Partly cloudy skies are expected overnight as lows drop to around 32°.

Sunday – Mostly Sunny – High 44° / Sun Night – Mostly Clear – Low 28°

Sunday will be cold for the most part. High pressure will settle into place to the west of the region, which will place us in northwest surface flow. Despite mostly sunny skies, highs will only top out in the mid 40s.

Weather Hazards

Severe Weather

Isolated strong to severe storms will be possible Saturday along a cold front. This will likely be a very thin line of storms capable of sporadic pockets of damaging wind. Wind gusts outside of thunderstorms could be well into the 40s, so be sure to anchor down trampolines and lawn furniture.
