Windy Days

It seems like it is has been windy every day for weeks lately. Historically speaking, the weather is doing what it has typically done this time of year when it comes to the wind. April is typically the windiest month of the year. The data in the chart below is for Waterloo. Friday is going to be another windy one with gusts from the northwest near 40 mph. The wind is light Saturday before a gusty south wind Sunday.

Peak Wind Gusts Sunday

Sunday (4/3/16) was a very windy and very warm day across the state of Iowa.  Temperatures reached the 70s and even lower 80s.  Here are the peak wind gusts from across the state.

iowa_wind_gust (1)Notice the isolated 70 mph wind gust in Johnson County.  That happened at the Iowa City Municipal Airport just after 6 PM Sunday.

Showers and a few isolated thunderstorms popped up during the afternoon, and that caused a small microburst in Iowa City.  We had very strong winds aloft in the atmosphere, and the rain helped to transport the very gusty winds downward from the cloud (downdraft), and that wind spread in all directions once it came in contact to the ground.  This can cause just as much damage as a tornado.

Fortunately, there was no damage at the airport from this small microburst.

The rain showers also made for some nice scenes across Iowa.  Many viewers sent in pictures of rainbows.

The wind lightens up for a few hours tonight under a clear sky. Late tonight the wind increases again from the northwest. A WIND ADVISORY is in effect Saturday for all of eastern Iowa with gusts to 45 mph.

The wind diminishes Saturday evening as the sun sets. A few flurries are possible Saturday morning otherwise it will be mostly sunny day. 

The chart below shows when the wind increases and decreases.

Another windy day, Sunday, but not as windy as Saturday. Wind gusts top out near 30 mph. It is also a southwest wind and that helps push highs into the 60s. Unfortunately the warmer weather won’t last more than one day. Highs drop into the 40s Monday.

Strong System Tracking Through

Spring-like weather tracks through the area over the next few days. Morning temperatures are above our normal highs, with slightly cooler air behind the current system. And while dewpoints are not very high by Summer standards, they are muggy for this time of the year.

MW Temp Dewpoint

Strong low pressure will track through the Midwest today and then stall as it occludes over the Great Lakes tonight and tomorrow.  Midwest FutureTrack AM SatRad - RPM 4km

Showers and thunderstorms tracked through early this morning producing gusty winds, some small hail, downpours of rain (around half in inch in some areas) and frequent lightning. As the main part of the system tracks in later this afternoon, more storms will develop. Some may be strong to severe with large hail the greatest threat, although damaging winds may also occur.

As the low’s center stalls over the Great Lakes, it will start to really strengthen the winds. This is the latest on one of our models… it has winds to 40 mph (gusting higher) by 4 AM Wednesday.

DMA FutureTrack Wind Speed - RPM 4km

 

All those with any sort of travel plans tonight and tomorrow should be aware that driving may be difficult. Those with high-profile vehicles will be most at risk, but winds at these levels will make it hard for any vehicle to stay on a straight away. Dirt, road debris and just the garbage that has accumulated in the ditches and streets over the winter will be easily picked up and blown around.

Windy Thursday

We’ve had quite a few windy days across eastern Iowa over the last couple of weeks.  The large low pressure system that brought snow from Arkansas to the northeast, and severe weather in the south and on the east coast has brought much of the Midwest and Ohio Valley quite a bit of wind out of the north and northwest.

windy stuffWe are situated in between the low pressure in the northeast and the high pressure in the central plains, creating those windy conditions.   As the low tracks away, our wind will die down.  Here’s a look at the trend for wind gusts over the next 48 hours.

Model Comparison windThe wind not only calms down, but switches to the southwest on Friday which will help push temperatures will be warming above average for the weekend.

The clouds we had today are slowly clearing out. Here is a visible satellite image from this evening.

The clear sky will give us a chance to see a few things this evening. First if you look west you can see Venus and the Moon. (Waxing Crescent with 12% of the Moon’s visible disk illuminated).

The other thing is the International Space Station. It will be visible at 8:51 pm for 4 minutes…traveling from the W to SSE.
