Soaking Rain Will Squelch the Summer-Like Heat

With record breaking 90s, this was probably one of the warmest Memorial Day weekend's we've had in awhile.

Records fell in Des Moines, Mason City, and Atlantic on Sunday.

Iowa will simmer down from the sweltering heat before the pendulum swings the other way and a chilly, soaking rain moves into the state.

Our weekend storm makes a clean sweep of the US.

The storm system that brought us the wind all weekend will be blowing the remnants of tropical storm Beryl and some Gulf of Mexico humidity out to sea. A drier and cooler area of high pressure will settle in briefly before a storm system crashing onshore in the Pacific Northwest migrates to Iowa. Dry air will limit the storm to produce only increasing clouds Wednesday. Moisture eventually catches the storm and Thursday could be a real soaker.

Dry air will break up some of the moisture to our south. Gulf
of Mexico moisture is the chief source of rain-making humidity
for Iowa in the spring.

A steady, substantial rain would be a nearly perfect scenario for our farmers, but a horrible forecast for anglers and outdoors enthusiasts on Thursday. Our storm system will take on winter-time characteristics meanwhile it will have access to summer-time moisture. Steady light to moderate rain with occasional thunder will blanket most of the state almost the entire day and highs will struggle. Some folks will not break out of the 50s Thursday.

The heaviest rain will be in central and western Iowa.
Dry air will evaporate rain some of the rain in eastern Iowa.

Rainfall amounts could approach 2", but some of the moisture to our south has been scoured out by Beryl and the weekend storm so we probably will pick up less than the computers think. It's still a good bet we will see more than 0.5" to 1" for most folks.

My beautiful girlfriend Heather caught this 19" bass on a
crankbait over a submerged road-bed. This fish was caught at
high noon with low barometric pressure as the front passed.

This summer I'll be focusing more on how weather affects fishing for the blog topics and I'd also like to shine the spotlight on local anglers. Tell me your fish story and what the weather was like when you caught him and I'll post it on the blog or I might even show it on TV. E-mail cconoan@myabc5.com and be sure to include your name, the picture and the weather conditions.
