HOT HOT HOT

Ok now back to our weather. I will start by saying our temperatures will be far from the numbers above. Actually, our highs this weekend and into next week will be a little below normal with highs reaching the 70s. Normal highs this time of year are in the mid to upper 80s.

Clouds have been moving south into Iowa this afternoon with a few light showers closer to the Mississippi River. Once the sun sets, most if not all of the showers will dissipate. Here is a satellite and radar image from this afternoon.

Blog Graphic 1

A trough of low pressure is forecast to cross Iowa from north to south Saturday with clouds and scattered light showers. Here is the WPC forecast map for Saturday afternoon.

June 28 Sat PM Sfc Map
Not everyone will get rain Saturday, but everyone has a chance of a shower or two. If you do get rain…the rain amounts would be light…mainly less than 0.25”. The map below shows the rain forecast from Friday evening to Saturday evening.

June 28 QPF

Sunday through Tuesday will be dry with comfortable humidity and highs in the 70s. Wednesday and Thursday there is a slight chance of showers/storms and then back to dry weather Friday. High temperatures at this point will be near 80 degrees.

June 27 latest_MSP_vis

Mostly sunny weather is expected Friday morning, but as a cold front from the north moves south clouds will increase in the afternoon with a chance of a shower/storm. Here is the WCP forecast map for Friday evening.

June  27 Fri Eve Sfc Map
The front will continue to drift south Saturday with a mostly cloudy sky and a better chance of showers/storms. The best chance would be in the afternoon. Saturday will also be much cooler with highs in the low 70s. The rain amount forecast is Friday evening to Saturday evening is less than 0.50” (see map below).

June 27 Sat QPF
A large ridge of high pressure will develop over the western half of the nation and remain there next week with HOT weather. Temperatures will be well above normal. At the same time there will be a trough of low pressure over the eastern half of the nation with cooler than normal temperatures, but very comfortable for the first days of July. Our temperatures will be influenced by the trough therefore; we will have cooler than normal temps next week. The humidity level will be less than it has been.

Isolated Storms for a Few Days


UPDATED at 4:15 PM

Tonight: A stray storm this evening then mostly clear. Low: 67-69. Wind: NW 5-10 mph.

Thursday: Partly cloudy with a 20% chance of showers/storms in the afternoon. High: 86-89. Wind: W 10-15 mph.

Wednesday: Partly cloudy with a 20% chance of showers/storms. High: upper 70s.

A stray shower/storm is possible this evening otherwise the sky will become mostly clear overnight. It will remain warm and muggy with a light breeze. Low pressure produced a few showers/storms across Iowa again today, but not as wide spread as we have had in the past few days. The visible satellite below shows the clouds remaining from the storms falling apart this afternoon.

June 26 latest_MSP_vis
The clouds will continue to clear and the sky will become mostly clear overnight. Thursday will start with out with plenty of sunshine. A few clouds will develop in the afternoon with a chance of a couple of showers/storms in the afternoon. As the sun sets, whatever rain is fall dissipate. Saturday will be another day with a chance of showers/storms.  The chart below shows the rain forecast during the next 5 days (Wed eve-Mon eve). The best news is if any rain falls the amounts would be light and have no impact on rivers.

June 26 QPF
High temperatures will cool to the upper 70s and low 80s through next week with lower humidity.

8:00 PM Weather Update

From WPC:

NEAR TERM MODELS….INCLUDING THE LATEST
HRRR…STRONGLY SUGGEST THE DEVELOPMENT OF AN MCS OVER IA AFTER 03Z…THEN HAVING IT TRACK EAST SOUTHEAST THROUGH 09Z. FLASH FLOOD GUIDANCE NUMBERS ARE LOW ACROSS EASTERN IA…NORTHERN IL INTO THE UPPER OHIO VALLEY…AND THE FORECAST QPF IS ABOVE THESE NUMBERS. HIGH PRECIPITABLE WATER VALUES (NEAR 1.75 INCHES) AND INSTABILITY
COULD ALLOW CONVECTION TO LOCALLY DROP 1 TO 2 INCHES OF RAIN IN AN HOUR…ESPECIALLY NEAR ANY CONVECTIVE CLUSTERS OR IN ASSOCIATION WITH AN MCV.

Translation of above text: the latest short term computer models show storms developing after 10 pm. Heavy rain (rates of 1-2″ per hour) is possible over saturated ground could cause flash flooding.

Storms are expected to develop in western Iowa in the next few hours. The storms will track east on the nose of a low level jet pushing into Iowa helping feed the storms.

June 25 Update

There is a risk of severe weather with a few of the storms. The main threat would be large hail and damaging wind in addition to heavy rain.

June 25 Severe
