The International Space Station (ISS) will be seen by most in eastern Iowa this evening. If you live along the Mississippi River you will not be able to see it (example Dubuque). But areas west of the river can. This will also be the last time to view it for a few weeks, for all of Iowa.

Time: 8:44 pm
Duration: 2 minutes
Patch: WSW to SW

The HEAT ADVISORY will continue through Wednesday as the heat index is forecast to reach 100-105 degrees in some locations. The hottest day through the weekend will be Friday with afternoon highs in the mid 90s. There is a slight chance of a stray shower Thursday as a warm front pushes east across Iowa.

Beginning Monday high temperatures will be much cooler with temperatures near 80 degrees and lows in the 50s. Until then, it will hot and humid.

We need some rain. Here are the rain totals as of today for the month of August:

A HEAT ADVISORY is in effect for all of eastern Iowa through Tuesday.  Wednesday and Thursday will be cooler by a few degrees, but still hot (near 90) and humid. I know that is not much of a cool down. Friday heats back up with highs in the mid 90s and the heat index between 100-105. Here is the forecast heat index across the nation Friday.

Aug 26 Fri Heat Index

Hottest temperatures so far this year (before today)
Waterloo: 96 (May 14 and July 17)
Dubuque: 91 (July 17 and 18)
Cedar Rapids: 94 (May 14)
Iowa City: 96 (July 19)

Record highs for Tuesday
Waterloo: 96 in 1955
Dubuque: 94 in 1895
Cedar Rapids: 97 in 1955
Iowa City: 99 in 1955

We will come pretty close to the records Tuesday. Forecast high temperatures will range from 94-97.

If you want cold weather, take a look at the temperatures (F) this afternoon in Antarctica (map below).

Compare those numbers to the heat index this afternoon at 3 0’clock.

Aug 26 Heat Index

The hot weather is all related to the upper level ridge over the center part of the state. Areas north of the “heat bubble” will get chances of showers/storms while areas under it will remain dry, hot and humid (that is where we will be).

It will remain hot and humid through at Saturday. Sunday and Monday is forecast to be in the mid-upper 80s. Winter is 116 days away.  In addition to the hot weather it will remain dry through the weekend.

Late last night and this morning, showers/storms moved through eastern Iowa. The heaviest of the rain fell north of Cedar Rapids. The southern part of the state saw very little rain in the last 24 hours. The map below shows the rain totals in the last 24 hours.

Aug 22 Rain Totals

I want you to notice the rain total at Dubuque, 2.25”. That amount is reported at the airport south of town. Here is a look at the rain totals reported in town compared to the airport.

The sky has been clearing from north to south this afternoon and there will be some locations that will have a clear sky this evening. Here is the visible satellite image from this afternoon.

You will be able to see the space station flyby. Here is the information:

Time: 9:35 PM
Duration: 4 minutes
Track: W to S

The recent rain and some clear sky tonight combined with little to no wind raises concern for areas of fog late tonight and early Friday morning. This is something we will monitor closely.

High pressure across the Midwest Friday will keep our weather dry with the humidity level lower than today. A warm front is still forecast to push east across Iowa Saturday. It now looks like there is a chance for showers/storms along the front. Here is the forecast position of the front Saturday morning.

Aug 22 Sat AM Sfc Map

After the front crosses eastern Iowa, the humidity level will go up again with dewpoints near 70 and high temperatures near 90 beginning Sunday and continuing through much of next week.
