Iowa Weather Report May 24th 2013

Posted on by

ROUNDS OF STORMS AHEAD: Today will be the last fully dry day for a while across the state with the next system approaching from the west. Sunshine will be plentiful across the state today with readings still several degrees below average with upper 60s to lower 70s possible. Storms will roll into the state late tonight into Saturday. This will continue off and on through at least Thursday and Friday if the GFS is correct. There will be some dry period in between rounds of storms and some sunshine is possible as well. Readings Saturday will be in the 60s across the state with the cloud cover. Sunday will also be cool with 60s to near 70 with some moderation in readings as we head into the following week. Severe weather is possible with any of the rounds of thunderstorms but not this weekend, at least on an organized basis. We’ll have to watch for any changes over the next few days regarding chances of severe weather with this slow moving system over the area through Thursday.

INTO JUNE: No real trends developing as we head into the sixth month of the year. The GFS shows a ridge forming around the second week of the month that will bring some (by this point) much needed dry weather to the state. It will also warm up as well if this pans out with some seasonal readings across the state. We’ll continue to monitor for any trends that form over the next few days regarding the first few days of Meteorological Summer.

Iowa Weather Report May 23rd 2013

Posted on by

MEMORIAL DAY WEEKEND: The next two days, Thursday and Friday will be filled with sunshine with a few passing clouds. Highs will be below seasonal averages for this time of year with 60s to lower 70s possible. The next storm system approaches from the west and stalls over the state through the Holiday weekend into the following week. This would bring repeated rounds of showers and thunderstorms across the state. Some of these storms could contain some severe weather but it’s too early to determine the kind and severity at this time, we’ll just have to keep an eye on it. This will not be an all day rain either with several hours of dry time each day. Readings will be in the upper 60s through the 70s through this time period with some areas cracking the 80s if enough sunshine peaks out. This system looks to continue at least through Thursday but we’ll have to keep watching for any subtle changes that may bring the precipitation to an end quicker.

JUNE: The GFS continues to show several storm systems effecting the state and region with showers and thunderstorms. Any of these storm systems could bring severe weather along with heavy rainfall as well. Flooding could become a concern if this was to pan out. While this could completely change on the next run we’ll need to keep watch for any continued trends regarding continued rain activity across the area over the next two weeks or so.

Iowa Weather Report May 22nd 2013

Posted on by

MID WEEK WET: Today will see the upper level system move over the state bringing with it some scattered showers to the area. It won’t be a heavy rain by any means with no one area getting more than a tenth or two of rain. Temperatures will be held down into the 60s to near 70 across the state today with the cloud cover that will be overhead.

FEW DRY DAYS: Thursday and Friday will be spectacular across the state with sunshine and temperatures in the 60s and lower 70s. There will be some increased cloudiness Friday as the next system does begin to approach from the west.

MEMORIAL DAY WEEKEND: This coming weekend doesn’t look to be the best with regards to doing anything outdoors. There will be several rounds of showers and thunderstorms throughout the holiday weekend (Saturday through Monday) with a slow moving storm system moving through the area. This will not be an all day rain by any means as there will be some dry hours intermixed during the day. Rainfall from this system could be at least an inch perhaps more with any areas that get repeated thunderstorms. There could be a threat of severe weather but it’s too early to determine that at this time given differences with other models. We’ll have to wait and get a better look at that in the coming days. Rain may continue into Tuesday and Wednesday with the system still across the Plains.

INTO JUNE: A ridge looks to set up across the Gulf Coast with a trough over the west. This would bring some warmer air into the state along with the chances for some showers and thunderstorms as well. This may change in future runs however.
