All of Iowa, Forecast

Iowa Weather Report June 10th 2014

CHANCES OF RAIN: The next few days will have some chances of rain around but they will be fairly remote at best. The best chance today will be mainly in the southeastern third of the state with a system that will slowly being moving to the east. The rest of the state will see partly to mostly sunny skies with readings in the middle to upper 70s. The southeastern third of the state will see readings in the lower 70s, if not in the upper 60s. Wednesday will see sunshine statewide with some clouds around as well as highs rebound back into the 70s to lower 80s. A cold front will move through the state late Wednesday night through the day on Thursday but even that chance of precipitation will be no more than a 20-30% chance. The GFS isn’t very bullish on a lot of rain with this system. We’ll see if that changes in the coming model runs. Friday will be similar in scope to Wednesday with mostly sunny skies around and readings in the 70s to lower 80s across the state.

WEEKEND WET: Another system will be moving into the state just in time for the weekend. What also will be returning this weekend will be muggy air, with dew points back into the 60s for most of the state while actual readings will be in the upper 70s to middle 80s. On Saturday, the best chance of seeing any precipitation will be across the western counties of the state while the rest of the state will be partly to mostly sunny skies with a noticeable increase in the cloudiness as we head farther into the afternoon and evening. The rest of the state will get in on the precipitation on Sunday across the state. It doesn’t look like it will be an all-day rain by any means and we could even see some sunshine around as well. However if we get some sunshine around, this may destabilize the atmosphere to bring about some stronger storms during the afternoon into the evening hours. It’s too early to determine the risk of severe weather this far in advance, especially with some model inconsistency, but it is certainly possible. We should have a better handle on this situation in the coming days.

LATER ON: As we head into a new work week, one system will be on the way out, but the GFS brings in another system later in the afternoon into the evening hours with more showers and thunderstorms possible. Highs on Monday look to be quite warm with the GFS suggesting readings in the 80s statewide with heat indices possibly approaching or exceeding 90. Any of these storms could also become strong to severe but as mentioned earlier, it’s still too early to determine the risk this far in advance. We could see a repeat of this again next Tuesday with a stalled frontal system close by along with readings similar to Monday in the 80s across the state.

THE DOLDRUMS OF JUNE: Heading into the extended period, the pattern to begin next week may continue through at least next Thursday before the pattern changes. Readings look to drop back into the upper 70s to lower 80s as the zonal flow becomes a northwesterly flow as a ridge tries to take shape to our southwest. This will also put an end to continuous chances of precipitation as well as lowering the humidity to a reasonable level. The flow looks to become zonal once again toward the end of the period with most of the precipitation north of the state however.
