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.

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.

Record Heat Possible This Weekend

This weekend’s forecast features the “triple H” = hazy, hot and humid. Plentiful sunshine helps temperatures today reach the 90s for all of eastern Iowa. On top of that, winds today come from a mainly southwesterly direction, meaning that it will continuously pull in warm air but also the winds pull humidity into the area. Winds today will be strong and gusty.

Air conditioning units will be on in full force this weekend. With heat and humidity like this, it is so important that you stay hydrated and always check the back seat before leaving your car.

We don’t see much relief from the humidity overnight. Lows fall to near 70° with breezy winds. Tomorrow, we make a better run for record highs. Once again, we soar into the low to mid 90s. Some record highs for the date tomorrow (June 11th) are from the 1920s and 1930s. Sunshine (and wind once again) will be abundant again for Sunday.

Increasing Humidity this Weekend

Our stretch of warm weather has begun in eastern Iowa. Today is one of the “cooler” days. Highs reach the low 80s to near 90° this afternoon. Humidity stays on the low side today, keeping things comfortably warm. A few showers and storms track through this afternoon into the early evening (severe weather risk is low). Not everyone sees rain today and some will only see sunshine on this Friday.

Tonight, as the temperatures fall, we feel a little more of the moisture in the air. If you’re planning a campfire, bring the water and a light blanket as overnight lows fall into the mid-60s.

Humidity slightly increases again during the day Saturday. Temperatures rocket into the 90s for most of the area tomorrow. The combination of heat and humidity brings the concept of heat index – how warm it feels outside.

Heat indices near 100° not only for Saturday afternoon but also on Sunday, as well.

Strong winds pick up on Saturday and continue into mid-week.

Rivaling Record Highs and Severe Storms Possible

After storms Monday evening, most of Tuesday will be pretty quiet. Partly to mostly cloudy conditions cover our skies. A front to our west will track very slowly to our area and that is why we keep cloud cover around. However, with us on the west side of the front, we’ll see strong southerly winds. Winds pull in more warm air and temperatures soar into the 80s and possibly low 90s (mainly along/south of I-80). Humid conditions will make it feel even warmer (hello heat index!).

Overnight, as the front tracks closer, we have the chance for showers and storms. Storms track through between 10pm and 2am Wednesday morning. Damaging straight line winds are the greatest threat, followed by hail and isolated tornadoes.

Scattered storms continue on Wednesday, some of which could be strong or severe. SPC issued a slight risk for all of eastern Iowa on Wednesday.

Check back for updates.

Record Cold Tonight

Record or near record low temperatures are expected by morning. The sky is clear tonight with a gentle breeze from the northwest. Wednesday is cold again with highs in the 20s under a mostly sunny sky. The wind switches from a light northwest wind to southwest wind. Clouds increase Wednesday night with low temperatures not as cold (teens).

Thursday and Friday will have a lot of clouds around. A slight chance of a rain/snow shower is possible Thursday and a rain shower Friday. High temperatures warm into the low-mid 40s both days. The wind is breezy from the southeast Thursday and from the northwest Friday.

The weekend temperatures are near or slightly above normal with a partly to mostly cloudy sky.

From “Summer” Back to Winter in 48 Hours

Not only did we break the record highs on Wednesday, we shattered them! Records were in the low to mid 60s and we ended the day in the upper 60s to mid 70s!

I hope that you enjoyed it, because Winter is tracking back in.  A strong low pressure system will track from Kansas through southeastern Iowa over the next 24 to 36 hours. This will bring a lot of wind along with a return to winter weather. Much of the viewing area will start off with rain, and even a few thunderstorms, later today into the evening hours.

The far northern counties could see snow taking over before Midnight. Heavy snow is possible there with areas to the south seeing a mix or just plain rain through the nighttime hours.

There is a VERY sharp cutoff between the snow and the rain.  Plus, the ground is pretty warm, so much of the early snow will melt. Having said that, if the snow falls very fast, it will be able to turn into a slushy mess.

As the system tracks to the northeast, more cold air will change all the precipitation to snow by tomorrow afternoon and evening.

Snow and snow showers will continue Friday night into early Saturday morning before we dry out.

Oh… and we will have a lot of wind!  Winds will gust to 30 mph today and up to 45 mph at times tonight with gusts to 30 mph tomorrow.  Any snow will be blown around quite easily and will help to reduce visibilities… no matter how wet and heavy the snow is.

Since this storm is still in Kansas, there is plenty of opportunity for it to change its track. And even a 50 mile shift in that track will change how much snow we end up with. Another problem with pinning down snowfall amounts… the ground is warm, so there will be melting at first, which decreases amounts. There is the possibility of thundersnow, which would increase snowfall amounts. Essentially, this forecast will likely change over the next several hours… and maybe through the entire event… but here is a general idea of how it looks right now.

This forecast will change as the fine details become more clear. Stay tuned to the latest forecast and download the Storm Track 7 app on your mobile device.

Record highs to snow chances

Today felt more like May than February. Daily record high temperatures were broken easily. At the same time all-time February record highs were broken.

Tonight: Increasing clouds late and cooler with lows in the upper 30s.

Thursday: Cloudy and cooler yet still above average again…just not 60s and 70s. Highs range from 45 north to 54 south. Rain moves into eastern Iowa during the afternoon.

Thursday Night: Far northern Iowa expect a wintry mix (rain/snow/freezing rain) with temperatures in the low 30s. It is warmer south with rain/thunderstorms. The wind increases from the northeast at 15-30 mph.

Friday: Rain chances continue through the day. A few hours of the day might actually turn sunny before clouding over again. Far northern Iowa rain mixes with snow in the afternoon.

Saturday: Light snow continues into the morning before tapering off by noon. A strong northwest wind, with gusts to 35 mph, continues to pull in cold air. High temperatures will be in the 20s and 30s across the area, with colder wind chills.

Sunday: Light snow showers are possible throughout the day with high temperatures in the 30s, and a SW wind 10-15 mph.
