Severe Storm Threat Today; Snow By The Weekend?

UPDATED POST:  Monday, March 6, 2017, 4:15 p.m.

After another balmy day with highs near 70° in the Quad Cities, conditions are favorable for severe storms tonight with damaging winds being the biggest threat.  We could also see large hail and a few tornadoes.

A “Tornado Watch” remains in effect through 10 p.m. for much of Iowa.  This includes our western counties of Jefferson, Johnson, and Washington.

The line of strong to severe storms is firing up over western and central Iowa this afternoon.  This radar image is from around 4 p.m.

This line of storms will race across Iowa and should be in eastern Iowa by 8-10 p.m. and east of the Mississippi around midnight.

I’ll continue monitoring the situation and let you know if the “Tornado Watch” is expanded eastward to include more of our counties and the Quad Cities.

If severe storms are not your thing, it’s looking more and more likely that we could be in for a decent accumulating snow starting Friday night into Saturday.

This is the latest GFS forecast map for noon Saturday!

I’ll have more on that tomorrow and the rest of the week.

Let’s get through tonight first.

Very warm temperatures are in the forecast again today with highs approaching 70°.

That’s the good news.

The bad news is that we could be seeing a repeat of last Tuesday’s weather with severe storms later today.

monday-severe-threat

Like last week, the biggest threat from the severe storms later this afternoon and early tonight will be damaging winds of 60 miles-per-hour or higher, large hail, and even a few tornadoes.

A line of storms will be forming across central Iowa this afternoon and will be moving into eastern Iowa by evening.

That line of storms will be crossing the Mississippi River by about 10 p.m.

The threat of severe weather should exit our eastern hometowns by midnight.

Temperatures will remain mild through Thursday in the 50s.

However, winter may return later Friday into Saturday.

It’s possible that we could be seeing an accumulating snow to kick off the weekend.

Snow Saturday Morning

There’s plenty of time to fine tune the forecast for the snow this upcoming weekend.

But, the big story today is the severe weather threat later this afternoon and early tonight.

Spring Yesterday & Now Back To Winter

After the record warm day Tuesday with a high of 69° in the Quad Cities, a strong cold front brought strong to severe thunderstorms to the Mississippi and Illinois Valleys.

At least 24 tornadoes were reported to the Storm Prediction Center Tuesday afternoon and Tuesday evening.

One of those was in Clinton County, Iowa, just north of the Quad Cities, near Low Moor.

Several tornadoes were reported in La Salle County, Illinois, about an hour or so east of the Quad Cities.  At least one person was killed and one injured near Ottawa, Illinois.

Near Kewanee and Galva, Illinois, in Henry County, there were several reports of large damaging hail.  Some of the hail was larger than golf balls.

The weather today, tomorrow, and Friday will be colder with highs closer to average for early March around the low-40s.

We could see a light wintry mix of rain and snow later today, but a more potent clipper moves through tomorrow afternoon and tomorrow night.

This could bring 1-2″ of snow to the north later Thursday and around a dusting to around one-half of an inch in the Quad Cities.

Warmer temperatures are on the way for the weekend.

Record Warmth, Then Severe Storms

UPDATED POST:  Tuesday, February 28, 2017, 11:13 a.m.

It’s now looking like that there’ll be a widespread severe weather outbreak across Illinois this afternoon and evening.

Here’s the updated categorical risk from the Storm Prediction Center.

That large area of “moderate” risk in downstate Illinois is rather ominous since it wasn’t on the earlier update at 7:37 a.m.

For the Quad Cities and our part of Iowa and Illinois, we’re still under the “slight” to “enhanced” chances of severe weather this afternoon and evening.

Our biggest threat will be wind damage, followed by large hail.

But, there’s still a chance of a few strong tornadoes in our area.

As of this update, there are no watches in effect.

I’ll keep you updated as needed today.

A storm system will bring us record or near record warmth today and then our first real severe weather threat this evening and early tonight.

severe-update

A warm front associated with that storm moved through eastern Iowa and the Quad Cities earlier Tuesday morning with non-severe storms.

High temperatures today will warm into the 60s to near 70°.  The record high in the Quad Cities today is 66°.  That was set just last year.

Interestingly enough, our record low for today was set two years ago at -18°.  What a difference a year makes!

With unseasonably warm temperatures in place this afternoon, strong to severe thunderstorms will be breaking out across Iowa and Illinois as the cold front arrives.

These storms could bring large hail, damaging winds, and even a few tornadoes, especially east of the Mississippi River.  This threat will last through the evening hours.

Tomorrow, as colder air comes in, the rain showers could mix with or change over to light snow.
