Iowa Weather Report June 20th 2014 – Iowa Weather Network Archives

BUILDING NOAH’S ARK: A brief break in showers and thunderstorms today with some sunshine and a few clouds around. It will remain warm and somewhat humid with readings well into the 80s and even a few lower 90s in the western counties of the state. The dry weather doesn’t last long as we head back into a rather rainy and stormy pattern once again late tonight through the weekend into early next week. Numerous rounds of showers and thunderstorms will be possible through this period with some dry periods during the day where we may be able to get some peaks of sunshine. However any sunshine we do get could lead to redevelopment of thunderstorms and perhaps some severe weather as well. Rainfall over the next five days could range between 1-2” with some areas getting more than that depending on where storms move over places repeatedly. There has already been a lot of rain across the northern half of the state and any new rainfall at this point would lead to more flash flooding and river flooding as well. Many rivers are running high at this point and several are under river flood warnings. We may see higher crests and longer durations of flooding if this pattern were to continue much longer.

FLOATING AWAY: The wet pattern looks to continue at least through Wednesday of next week before we get some drier weather on Thursday and perhaps even next Friday as well. Readings look to be in the 70s and 80s Thursday and Friday of next week after readings mainly in the 80s for most of the week. Given the wild swings in the weather, we will have to see if this dry period does continue in future runs, or the duration of the drier weather changes as well.

INTO JULY: Seasonal readings with periods of rain continue into the extended period with some warm days intermixed as well. The model does show a heat ridge developing to our west which will begin to influence our weather toward the 4th of July Holiday with readings possibly getting into the 90s if this is correct. This would also turn the rain off as the main storm track would move northward. Given the amount of rain we will have received by that point (rain that has fallen and rain forecast to fall), we could see heat indices near heat advisory criteria, but again this is still far out in advance and can change with the next model run.
