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

HEATING UP: The warm up looks to continue with sunshine around today with a few afternoon clouds. Highs today will be in the 80s across the state. Heading into the new work week, temperatures will rise into the upper 80s to the lower and middle 90s. With higher humidity levels across the state, this will lead to heat indices in excess of 100 in some areas. Heat Advisories may have to be issued depending on the heat index forecast in certain areas. There is a slight chance of seeing a shower or storm around but those chances are less than 20% at this point. The better chances look to come late Monday night through Tuesday and Wednesday. This will not be an all-day rain by any means as there will be some breaks with sunshine. Highs Tuesday will be in the 80s and 90s with heat indices possibly approaching or exceeding 100 again. Wednesday will see drier air move in as the storm system moves off to the east. Temperatures will drop back into the 80s with possibly some upper 70s in northeast Iowa with some early day precipitation followed by clearing.

SHORT BREAK, THEN HUMID AGAIN: Thursday will see mostly sunny skies around with readings similar to Wednesday, in the upper 70s to middle 80s across the state with low humidity around. Unfortunately, this won’t last long as a warm front moves back into the state late Thursday through Friday with a chance of showers and storms. This will also bring the humidity back into the state again as dew points will rise back into the 60s by Friday and Friday night. Highs on Friday will be in the upper 70s northeast to the upper 80s southwest, mainly due to the amount of clouds that will tend to keep the temperatures lower.

NEXT WEEKEND AND ON INTO AUGUST: Scattered showers and storms will dot the state throughout the weekend but not the whole weekend. The best chances look to come early on Saturday and on Sunday afternoon as a low pressure center moves in from the northwest. Readings will be mainly in the upper 70s to lower and middle 80s at this point. Looking into the extended period, the flow continues to come from the northwest with several systems from time to time. This will keep temperatures near seasonal levels at least through the first few days of August. We’ll see if this pattern continues on forthcoming model runs.
