Blizzard Warning

15 Jan 2021 05:46 AM
As shown by the featured map, the NWS has a Blizzard Warning in effect for today with snow and blowing snow creating whiteout conditions. This is all thanks to a very large storm system whose surface low pressure center is currently near Waterloo this Friday morning. This storm marks the end of a very quiet stretch of winter weather this January. The near term forecast after this storm does not look too bad, with only slightly cooler temperatures next week.

Add SQ.W to the listing

11 Dec 2019 05:34 AM
The IEM attempts to curate a rigorous accounting of the watch, warnings, and advisories issued by the National Weather Service. The NWS Offices serving Iowa have a new alert type this winter season called the Snow Squall Warning. It is abbreviated as SQ.W in their text product alerts. NWS Davenport issued such an alert on Monday for the quick hitting snowfall that was causing travel difficulties. The featured chart presents a yearly accounting of the unique number of tracked alert types issued by NWS Davenport. The number of distinctly used Valid TIme Event Codes (VTEC) phenomena and significance values per year is shown by the top panel and the bottom panel explicitly lists them out. Note that there are other alert types not covered by this presentation. This is for only those that contain VTEC.

Unique Alert Counts

10 May 2016 05:35 AM
Severe weather was abundant on Monday with damaging storms reported from Iowa to Texas. The NWS Des Moines issued a number of Tornado and Severe Thunderstorm Warnings along with a Severe Thunderstorm Watch. The featured top chart looks at the unique number of VTEC coded alerts that the office issues each year. The bottom chart explicitly lists out the unique codes used each year. Warning procedures have changed over the years, so some warning types are no longer used. This chart only covers those products that have Valid Time Extent Coding (which is most of the alert types), so the actual number of alert types is higher than shown.
