This is a test post.
I plan to depart for southwestern Iowa shortly, follow the links below for the latest information on today’s severe weather threat. The live coverage link will have my video stream as well as here on my website.
A Severe Thunderstorm Watch is likely for Western Iowa, areas along and west of US Highway 71, for damaging wind potential and possibly some large hail as storms ongoing in Nebraska and Iowa make their way into the state.The area circled in red on the map below is the area being considered for the watch.
I’m currently sitting in Sioux City in advance of tomorrows severe weather potential, with the whole state having a chance at severe weather.
I have been terrible about keeping this updated lately. I am looking at chasing this weekend, but haven’t ironed out the details yet. It does however appear that anyone with outdoor plans for this weekend into Monday in Iowa and surrounding states should keep an eye on the weather.
…DANGEROUS FIRE WEATHER CONDITIONS THIS AFTERNOON…
.STRONG SOUTH TO SOUTHWEST WINDS OF 20 TO 25 MPH AND GUSTS TO NEAR
40 MPH…COMBINED WITH VERY LOW RELATIVE HUMIDITY WILL RESULT IN

WESTERN IOWA BY THIS AFTERNOON AND INTO THE EARLY EVENING.

THE NATIONAL WEATHER SERVICE IN DES MOINES HAS ISSUED A RED FLAG
WARNING FOR EXTREME FIRE CONDITIONS…WHICH IS IN EFFECT FROM

A RED FLAG WARNING MEANS THAT CRITICAL FIRE WEATHER CONDITIONS

CONTRIBUTE TO EXTREME FIRE BEHAVIOR.
The weather in the state is fairly active this morning as shown on the watch/warning map below.
Severe Thunderstorm Watch is in effect for portions of south central, southeast, and east central Iowa into adjacent portions of Missouri and Illinois until 5 PM. Recent rainfall has reduced, if not resolved the drought conditions in portions of the state with flood watches and warnings now in effect in many areas including parts of the Mississippi.
