THE COMBINATION OF VERY DRY CONDITIONS…AFTERNOON TEMPERATURES FROM 95 TO 105 DEGREES…HUMIDITY FROM 20 TO 40 PERCENT AND SOUTHWEST WINDS OF 10 TO 20 MPH WITH HIGHER GUSTS…WILL COMBINE TO PRODUCE CONDITIONS FAVORABLE FOR WILD FIRES ACROSS MUCH OF CENTRAL AND SOUTH CENTRAL IOWA THIS AFTERNOON.

THE HOT AND DRY WEATHER PATTERN WILL REMAIN OVER THE AREA THROUGH TODAY. DURING THIS TIME…REFRAIN FROM OUTDOOR BURNING AND BE VERY CAREFUL WITH SMOKING MATERIALS. SEVERAL COUNTIES HAVE BURN BANS IN EFFECT. PLEASE CHECK IN YOUR COUNTY BEFORE BURNING. ANY OPEN FIRE COULD SPREAD EASILY.

DES MOINES, Iowa (AP) – The National Weather Service says heat relief will not be soon in coming for Iowa and Nebraska.  A weather service warning about excessive heat remains in effect until Wednesday afternoon or night in west-central and southwest Iowa and in southeast Nebraska.  The warnings are issued when the service experts believe dangerously high temperatures will occur in which “heat and humidity will combine to create a dangerous situation in which heat illnesses are likely.”
 
The century mark was breached in both states on Sunday. The air temperature hit 104 in Des Moines and 105 in Omaha, for examples. In Atlantic, we topped out at 100-degrees. Humidity across the region made it seem hotter, though.
