Near Record Highs Friday

We are ending the summer on a HOT note, with high temperatures in the 80s and 90s across eastern Iowa over the last few days.  In fact, Cedar Rapids tied the record high for September 21st at 93°, which was last reached on this date in 1920.  The Autumnal Equinox is at 3:02 PM Friday.  However, it’s going to still feel like we are in the middle of summer.  High temperatures will be very close to record for September 22nd.

There seems to be a better chance at tomorrow being the warmest start to Fall ever across eastern Iowa.  Keep in mind, each year the Autumnal Equinox may vary between September 22nd or September 23rd.

However, if you are one of those people ready for fall-like weather, we don’t have to wait too long.  The long-term trends point to cooler temperatures by the middle of next week, and at or below normal temperatures as we head into the first week of October.  This is from the Climate Prediction Center.

Dry Conditions Across Iowa

As we’ve reported over the last several weeks, we could use some rain across the state of Iowa, especially the southern portion of the state.  Here’s the latest Drought Monitor that was released Thursday morning (8/31/17).

August was an abnormally dry month, and it appears the first half of September (at least) will be dry as well.  Here is the Climate Prediction Center’s outlook for precipitation, showing a good chance for below average rainfall.

Here’s a look at the average amount of rain that should fall during the month of September for Waterloo, Dubuque, Cedar Rapids and Iowa City.

Moderate to major flooding on local rivers

Due to the recent heavy rainfall between 2 and 10 inches across northern parts of the KWWL viewing area, local rivers are experiencing quick rises, leading to moderate to major flooding.

The Volga River at Wadena, Volga and Littleport is experiencing major flooding as of Saturday afternoon, forcing evacuations in Volga.  The Turkey River at Elkader and Garber remains at minor to moderate flood stage, and is forecast to continue to rise through Sunday afternoon.

The Wapsipinicon River near Tripoli is experiencing minor flooding (there is no forecast point for the river near Tripoli).  However, downstream in Independence, the river is expected to rise rapidly Saturday night into Sunday.  The same can be said for the Maquoketa River at Manchester.

No flooding is currently forecast on any part of the Cedar River.

Isolated showers/storms Monday

A spotty shower is possible during the afternoon but the bulk of the rain as tracked out of the area. Highs today remain cooler than normal – in the upper 60s to low 70s. Clouds track out this evening, leaving us with clear skies. Expect another cool night, with lows falling to near 50°.

Sunshine is the name of the game tomorrow, along with warmer temperatures. Everyone sees the 70s for highs Tuesday, with some upper 70s possible to the south. We can thank a southerly wind flow for the warming trend that begins tomorrow.

Strong Storms Possible Wednesday and Thursday

Welcome to the first full day of summer 2017. The season and the day started very tranquil. However, with a warm front approaching from the southwest through the day, things start to change up. Showers and storms move through the state this morning and possibly again for later in the day. Some of those storms may produce strong winds and large hail.

Winds increase in strength from a southerly direction. Dew points and humidity increase through the day, as well. Highs today reach near 80° closer to the Minnesota line to the mid-80s in our southern towns. A breezy afternoon is on the way.

Overnight lows will not cool much thanks to the increased humidity – only getting into the mid to upper 60s.

Humidity continues into Thursday. With us in the wake of the warm front Thursday and the higher humidity, it will feel like summer.  That does not last very long as a cold front will sweep through eastern Iowa tomorrow. That second front brings more storm possibilities to us…and potentially some strong to severe storms.

June Rainfall Update

As you all know, it was a very dry and warm start to the month of June across eastern Iowa.  Recent rains have put a slight dent in the rain that we desperately needed, especially in Iowa City.  However — Waterloo, Dubuque and Cedar Rapids are still running a little bit below average through June 18th.

We are heading into an active summer pattern in the week ahead, with off and on rain and storm chances beginning Monday.  (By the way — summer officially begins 11:24 PM Tuesday)

The Climate Prediction Center has a chance of above average precipitation June 24th through 28th, so there is still time to catch up.

Be sure to keep up with the latest Storm Track 7 forecast.

Father’s Day Forecast

Happy Father’s Day to all of the dads across eastern Iowa.

Your day will be cooler than Saturday. Highs today warm to the 70s across the board. The morning remains dry before a chance of showers tracks in for the afternoon hours. A rumble of thunder isn’t out of the question this afternoon. Depending on where exactly the rain moves through, the breezy wind may be more of a disturbance for your plans than the rain chances today.

Overnight, we cool into the mid to upper 50s. Another cool day comes on Monday as highs once again reach the 70s. Storm chances return tomorrow during the afternoon and into the evening. Warmer air moves in Tuesday (just in time to start summer late Tuesday night).

Storms Possible Tonight and Wednesday

The evening is going to be dry with temperatures slowly falling into the 80s. Storms are possible late tonight…after 2 or 3 AM. There is no risk of severe weather at this time with the overnight storms. Due to the high humidity level, the overnight lows only drop to the low 70s.

The showers/storms end early in the morning. Wednesday turns out to be another hot and humid day with temperatures near 90 degrees. Storms redevelop after 2 or 3 PM with a few storm potentially severe with large hail and damaging winds as the primary threats. The storms end during the evening then the sky becomes mostly clear.

Low temperatures Thursday morning and Friday morning are a little cooler…mid 60s…signs of slight less humid conditions. During the day it is still hot with highs near 90 each day. Thursday is mostly sunny with a slight chance for an afternoon storm. A little better chance of storms late Thursday night into Friday morning.

A cold front finally pushes through Saturday with a chance of more storms. The best part of this will be the cooler and less humid conditions to follow Sunday through Tuesday.

Hot and Humid then Slight Risk Late Sunday Night

This stagnant weather pattern we have been in continues again today. A stationary front sticks around to the north and a front lingers to the west. In between those two boundaries, we have a continued flow of air from the southwest. The air that is flowing in from the southwest is very warm and quite humid.

If you were looking for a break from yesterday’s heat and humidity…today won’t be your day. Highs reach the low to mid-90s from north to south.

A strong southwesterly wind unfortunately does not provide much relief from the summer-like conditions.

The front that sits to our north could fire up a few storms in our extreme northern areas, but the bulk of the storms stay into Minnesota and Wisconsin.

Another humid evening is on the way across the area. Lows only fall to near 70° with breezy winds. A stray storm is possible overnight, as well. A few more clouds track in for Monday, which may keep it a couple of degrees cooler than Sunday. Temperatures still land above average for this time of year.
