Iowa Weather Report June 28th 2015: Just Another Summer Sunday

NORTHWESTERLY RAINS: The flow will be coming out of the north and northwest through the week with some chances of showers and thunderstorms possible. The best chances look to be today into Monday and Wednesday night through early on Friday. We can’t rule out possible chances any other day, but the chances then are slim to none. As for today a system will be dropping in from the north and northwest, with showers and thunderstorms possible. We will see some activity in the morning and some redevelopment later in the afternoon. Some of those storms could become strong to possibly severe, especially in the southern counties. Highs today will be held down slightly due to the amount of cloudiness that is expected. Readings in the 70s will be common. As we move into the new work week, readings will be in the 70s and 80s for the most part with some dry days and some wetter days as well Monday for example should be mainly dry in the western counties with some scattered showers and or storms in the east. Tuesday and Wednesday will be dry. Thursday will be wet for the most part and Friday should be mainly dry at least from late morning onward (except perhaps in the eastern counties).

SHOOTING OFF THE ROCKETS: Looking at the Independence Day Weekend, the weather for the 4th looks to be great with plenty of sunshine and virtually no chance of rain at this time. We’ll keep a careful watch on that. Readings for Saturday will be in the upper 70s to middle 80s across the state. The second half of the weekend looks a bit stormier as a system will be moving in from the west by late in the day. This would bring some showers and thunderstorms by the afternoon hours to our western counties. These will spread eastward during the evening and overnight hours.

THOSE LAZY HAZY CRAZY DAYS OF SUMMER: Going into the extended period, the ridge over the west begins to slowly move to the east at the start of the period. The GFS still has us in a northwesterly flow, however temperatures will be at seasonal levels for the most part. The model run is also showing active weather around as well with numerous showers and thunderstorms possible. The ridge in the west begins to flatten however the model run shows a storm system moving quickly over the region around the 11th that looks to reinforce the northwesterly flow across the area through the end of the period. This would mean temperatures would stay at or slightly below seasonal levels for the time being. Still not convinced yet on this solution, but we’ll keep looking at it.
