STORMY START, THEN COOLER WEEK....

It was a toasty weekend across the Midwest with temperatures in the 80s and 90s both days. We lost the wind on Sunday and had the warmth (and some humidity to boot!).

Here's a look at the temperatures Sunday afternoon:

A cold front will start to move through overnight into Monday morning. This will bring much needed rain to the Midwest and the potential for some strong storms. Here's the latest outlook from the Storm Prediction Center:

There was a northwestern shift in this outlook and it's really just dependent on the timing. There may be a few showers/storms Monday morning, then storms become more likely in the afternoon and evening.

Here's a look at the timing on the HRRR model from Monday morning through Tuesday afternoon:

The main threat would be gusty winds and perhaps some hail. Because of the clustery nature of the storms the tornado threat is fairly low.

Here's a look at the rainfall totals on the hi-resolution NAM through Tuesday afternoon:

The higher totals (around an inch or more) will be where the thunderstorms set up, so that is still subject to change.

Behind this system temperatures do drop and we'll be below normal for the rest of the week. In fact, the Climate Prediction Center keeps us in the chances for below normal temperatures through May 12th:

Here's a look at the temperature trends for the Quad Cities:

And Cedar Rapids:


The 80s are going away for a while, but a lot of us do need the rain! RK
