Current riskA low-level risk on Tuesday afternoon and night.

Current confidence level: Medium.

Comments:  I will monitor Tuesday afternoon and night.  A few storms could become severe.  Wind and hail are the main concerns.  The risk is a bit higher over southeast Missouri.  The tornado threat is low.

The graphic below (the left side of the graphic) shows you the level one (dark green) and level two (the yellow color) risk zones.

The level two zone has a slightly higher risk of severe weather on Tuesday afternoon and night.

Forecast discussion

  •   Unsettled weather this week.  On and off shower and thunderstorm chances.
  •   The risk of severe weather this week is low.  Perhaps not zero.  I am watching Tuesday afternoon and night.
  •   Rainfall totals of one inch are likely across the region.  Locally higher amounts are possible.
  •   A bit warmer today through Wednesday.  Then, a bit cooler.
  •   On and off cool shots into mid-May.

What is the primary weather concern today and tonight?

Scattered showers and thunderstorms today and tonight.  Chances are fairly low today, but increase late tonight.

See the rain probability graphics below.

.

Here are the early morning current conditions.  These are the 4 AM readings.


.

It will be a bit warmer today.

Some areas had frost yesterday morning.  Temperatures fell into the 30s over much of the region.  Some low forties, as well.

There are some storms early this morning across portions of the I-64 corridor and the Evansville Tri-State area.

You can see those storms on this 5 am radar snapshot.

Today, southwest winds will become breezy. Because of the stronger winds, there may be rough conditions on area lakes and an increased fire danger.

A lake wind advisory has been issued for the area today.  Boaters use care.

A large area of showers and scattered thunderstorms will spread southeast across the region tonight and continue into Tuesday morning. Rain chances will be high (80–100%) Tuesday through Tuesday evening.

Some showers will likely continue into Wednesday. Rain chances will range from about 30% in northern areas to 60–70% in the southeast (see the graphics below). A few thunderstorms are still possible near the Missouri/Arkansas and Kentucky/Tennessee borders.  Rain should gradually end from northwest to southeast on Wednesday night.

A few thunderstorms on Tuesday afternoon and night could be intense, with gusty winds and hail.  Overall, there are still many questions about whether a few storms will become severe.  Especially over southeast Missouri.

Cloud cover and ongoing rain may keep the risk shunted south of us.  I will be monitoring it, as always.

Most areas are expected to receive around 1 to 1.75 inches of rain. There is a 60–80% chance of getting more than 1 inch, and a 15–40% chance of getting more than 2 inches.

Here are the anticipated rainfall totals.  As always, they will vary based on where thunderstorms occur.

Thunderstorms will enhance totals.

Looking ahead, there is a small chance of showers and thunderstorms on Friday afternoon into Friday night and again on Sunday.
