August 5: Unsettled Weather Ahead

Today’s weather was absolutely PERFECT — hope you were able to get out and enjoy it!

Today’s beautiful weather will be replaced by an unsettled weather pattern beginning tomorrow, and lasting through most of the upcoming week.  High clouds will spread over the Midstate tonight, but temperatures will still drop to the low 60s by early Sunday morning:

We’ll warm up to the mid to upper 80s by Sunday afternoon:

Showers and thunderstorms will become more likely throughout the afternoon and evening, as shown on the RPM model’s radar simulation:

A few of those storms could be strong — the Storm Prediction Center has included our westernmost counties in a “Marginal Risk” (level 1 of 5) for severe storms:

That means there will be numerous storms, a few of which could produce damaging winds.  Just be flexible with any outdoor plans Sunday afternoon and evening — if there’s lightning in your neighborhood, head inside until the thunder fades.

The best chance of widespread rain and storms will shape up late Sunday night and early Monday, but the severe weather threat should diminish once the sun goes down:

Off-and-on showers and storms are in the forecast throughout the work week, thanks to an unusual August weather pattern — a strong area of low pressure centered way up in Canada will remain parked in place, sending little atmospheric ripples down our way:

It’s a notoriously hard-to-forecast pattern, so while our rain/storm chances will go up and down throughout the week, you can count on some changes to the details of the forecast on a day-to-day basis:

Be flexible with your outdoor plans throughout the week, and stay plugged into the forecast for any changes.  Because of the rain chances, temperatures will run below normal most of the week, mostly in the mid 80s for highs.

I’ll already have some new data to look at between now and News 4 at 10pm, so I’ll have an update then!
