SUNDAY NIGHT UPDATE: 9:40 p.m.
For my family and friends back in Kentucky and Illinois, a “Tornado Watch” remains in effect until 2 a.m. Monday. There are several severe storms racing into western Kentucky and southern Illinois with winds of 55-60 miles-per-hour, large hail, and heavy rains that could cause flash flooding. Remember, a “Tornado Watch” means conditions are favorable for severe storms that could cause tornadoes.
As of this evening, there have been seven reported tornadoes across eastern Arkansas and those storms are moving into the Memphis area.
Back here in the Quad Cities, eastern Iowa, and northern Illinois, we’re socked in with dense fog with visibilites of one-quarter to one-half mile. This will persist until around 3 a.m. At that time, the winds will become gusty and this will improve the visibilities.
However, the rain will become mixed with snow around Iowa City and Dubuque by morning and this will become widespread Monday for all of us with temperatures falling into the upper-20s and low-30s. Accumulations should stay at one inch or less.
Everyone have a great night and a great week ahead.
We’re going to see a little bit of everything over the next 24 hours across the Mississippi and Illinois Valleys.
Low pressure moving up from the southwest will track just to the southeast of the Quad Cities tonight and Monday. This is bringing slightly milder air to our southern hometowns Sunday night.
Thunderstorms over the Ohio Valley may be close enough to produce a few rumbles of thunder tonight in our southern hometowns.
Otherwise, the melting snow from Sunday is adding much more moisture to the air and producing dense fog.
There is a “Dense Fog Advisory” for much of the area on both sides of the Mississippi River until 3 a.m.
Visibilities may reach less than one-quarter of a mile in these locations.
Light rain will become likely Sunday night and by daybreak Monday, this rain will change over to light snow northwest of the Quad Cities, to the west of Dubuque.
This will spread across all of the area Monday with temperatures falling into the low-30s after peaking in the mid-to-upper-30s.
Winds will be very blustery later tonight through Tuesday with sustained winds at 22-32 miles-per-hour (mph) and gusts hitting 40 mph at times.
Sunshine returns Tuesday and it’ll be cold with highs in the upper-20s.
Milder air and some clouds fill the skies Wednesday with more sun by Thursday. Highs both days will be in the 30s.
By Friday, we could see a little light snow and then a quick blast of cold air Saturday. There are indications that highs might only be in the low-20s Saturday.
Take it easy out there tonight and Monday.
