T-storms Ending…New Drought Map…Drought of Tornadoes

Ed's Weather Journal

The isolated storms that left us with about another half-inch of rainfall..are moving out of the state.

We had a ton of rainfall today in the Greene…Boone and Story County areas. Over 2 inches of rain fell in Perry and Ames. Perry RainAmes Rain

The extra rainfall is not welcomed by farmers who have been waiting to get their seeds in the soil. It will be a drier weekend and even warmer with dry conditions most of next week that should help many get the planting underway.

The latest drought index was issued today…and over half of the state is drought free. That includes Des Moines. There are still varying levels. Not a huge surprise after the amazing amount of snow and rain this month. drought_map

It has been a long time since a tornado set down in Iowa. No complaints…but as of today it has been 350 days since a tornado was reported in the state. We are just five days away from tying the old record set in the 50s.

…ON THE CUSP OF STATEWIDE TORNADO CESSATION RECORD…

THE LAST TIME A TORNADO OCCURRED IN THE STATE OF IOWA WAS ON MAY
24TH 2012 IN FAYETTE COUNTY. AS OF THE END OF THE DAY ON
WEDNESDAY…IT HAD BEEN 349 DAYS SINCE THAT TORNADO OCCURRED. THE
RECORD LENGTH OF DAYS BETWEEN TORNADO OCCURRENCE IN THE STATE IS
355 DAYS SET BETWEEN THE DATES OF MAY 5 1955 AND APRIL 26 1956.
THEREFORE…WE ARE SET TO TIE THE RECORD ON TUESDAY MAY 14TH AND
BREAK IT ON THE 15TH. AT THIS TIME…THE SEVERE WEATHER THREAT
APPEARS MINIMAL THROUGH EARLY TUESDAY. HOWEVER…A FRONT WILL
APPROACH THE STATE LATE TUESDAY WITH AN INCREASING THREAT FOR
THUNDERSTORMS.

THIS STREAK IS RATHER IMPRESSIVE ON ITS OWN. HOWEVER…REPORTING
STANDARDS IN THE 1950S WERE NOT NEARLY AS ROBUST AND COMPREHENSIVE
AS THE PRESENT. DIGITAL TECHNOLOGY AND NEARLY UBIQUITOUS USE OF
CELL PHONES ALONG WITH EDUCATION…STORM CHASING…AND SPOTTER
NETWORKS OF TODAY AMONG OTHER THINGS HAVE FACILITATED THE
OBSERVING AND REPORTING OF TORNADOES. THEREFORE…THE LIKELIHOOD
OF HAVING A TORNADO OCCUR AND NOT BEING OBSERVED OR EVEN OBSERVED
BUT NOT REPORTED WAS MUCH GREATER IN THE 1950S THAN WHAT WOULD BE
EXPECTED TODAY WHICH MAKES THE CURRENT STREAK STAND OUT EVEN MORE.

And today we had cold-air funnel clouds in the Fort Dodge area. Bruce Becker took a picture of one of the funnel clouds north of Fort Dodge this afternoon. Funnel Cloud
