Warmer Sunday, Windy Monday

If you didn’t get enough of the sun yesterday, you’ll have another chance today. Also… if yesterday wasn’t warm enough for you, today should be better. Highs today, thanks to a southwesterly light wind, reach the 70s across eastern Iowa. That’ll be 5-10° above normal for the date. Today’s checklist once again will feature sunglasses and allergy medicine. Pollen counts stay high through midweek.

Lows fall into the 40s tonight before another mild day (again, with the southerly wind). Monday may be a couple degrees cooler with increasing clouds later in the day. Most of the area once again warms into the 70s. Winds become stronger ahead of a cold front that tracks through Tuesday.

Winds stay breezy as the front crosses the region Tuesday. We could squeeze a rumble of thunder out along with showers Tuesday.

Mild Saturday, Warmer Sunday

Anyone up for a good dose of sunshine?

The entire weekend features plenty of it for eastern Iowa. High pressure moves over head for Saturday and Sunday bringing clear skies. Highs Saturday will be cooler but land near average for the date – 63-65. Clear skies continue tonight.

 

Winds change direction overnight, becoming more northwesterly than northeasterly, signaling the motion of high pressure tracking to the east and away from the state. However, with that movement comes an eventual southwesterly wind that pulls in warmer air for Sunday. Highs Sunday – 68-72.

Windy Conditions

It was a windy Thursday behind the low pressure system which produced rain/storms in Iowa Wednesday. The map below shows the peak wind gusts Thursday.

The wind lightens up a little tonight before it increases again Friday. Wind gusts could be near 25 mph Friday.

Enhanced Risk for Eastern Iowa Wednesday

The entire KWWL viewing area is at risk for severe weather this afternoon and evening. Far northern counties are under a “slight” risk but most of the area is under an “enhanced” risk. Those under the enhanced risk have a greater chance of seeing the severe weather later today.

We’ll have all the ingredients in place for severe weather today. The biggest concern with severe weather today is large hail, followed by damaging winds and then tornadoes.

Storms will be out of eastern Iowa by midnight. A few lingering showers continue early Thursday morning.

Behind tonight’s system, clouds clear through the day tomorrow. Winds strengthen tomorrow, as well. Temperatures fail to reach our normal highs Thursday through Saturday and only warm to the upper 50s/low 60s. Our weather stays quiet and pretty mild through Monday. Windy conditions return Monday ahead of our next system Tuesday.

Severe Weather Potential Wednesday

The sky is mostly cloudy tonight with a few showers possible. Lows tonight hover around 50 degrees. Showers and storms will come in two waves. The first round of showers/storms will come around mid morning. Non-severe storms are expected with those. The second round of showers/storms will be during the evening. This is where we have the best chance of any severe weather. Severe threat with any of the storms would be large hail, damaging winds, heavy rain and isolated tornado. The storms end before midnight followed by the wind increasing. The wind remains strong as it turns to the northwest Thursday. Clouds clear throughout the day as cooler air moves into the area. Friday through Tuesday is dry with varying cloud cover. High temperatures will be near or below normal for this time of year with highs in mid 50s to low 60s.

Rain/Storms Possible Friday and Saturday

A few showers are possible tonight under a mostly cloudy sky. Temperatures are mild for this time of year. Normal lows are in the mid 30s, but tonight our lows will be in the mid 40s north and low 50s south.

The wind increases from the southeast Friday at 10-20 mph. Temperatures warm into the mid 60s north to low 70s south. Scattered showers and storms are possible Friday with the best chance in the afternoon and evening. The showers/storms taper off by midnight Saturday night.

Another round of showers/storms are possible Saturday with the best chance again in the afternoon and evening. The wind is stronger from the south pushing highs into the 70s. Any storm may produce downpours, gusty winds and small hail. Rain amounts could be around 1.00″ from Thursday evening through Sunday evening.

Sunday might turn out the be the best day of the weekend with no rain and a lighter wind. High temperatures are a little cooler…mid 60s.

The chance of showers/storms next week will be Tuesday and Thursday. High temperatures most of next week are in the low 60s.

Temperatures warm to the upper 50s and low 60s by the afternoon.

 


 

Rain and scattered storms move back in Friday morning and continue on and off through Saturday. Rain amounts from these two days could add up to around 2.00”.

 

 

Sunday is dry with a mostly sunny sky and slightly cooler temperatures with highs in the low 60s. Sunrise is at 6:26 Sunday.

Clearing Today but Clouds Return Wednesday

Sunshine returns to eastern Iowa this afternoon. After starting the day under an overcast sky, high pressure begins to build in. It will also be cooler today. Highs reach the low to upper 50s from north to south. Mostly clear to partly cloudy skies settle in across the area tonight. Lows fall to the mid-30s through low 40s.

High pressure begins to track away from us tomorrow. Due to a clockwise rotation of air, we’ll have a southerly wind as the high is to our east. Southerly winds mean warmer air returns for the midweek. The reason we see warmer air will be a contributor to increasing clouds tomorrow afternoon. A rain-making system will move toward eastern Iowa on Thursday.

A warm front pushes another surge of warm air into the state Friday, but also another chance for showers and breezy winds.  A cold front Saturday may fire off thunderstorms for the first half of the Easter weekend. Easter Sunday looks dry and mild.

Rain Chance Monday Evening

After overnight storms, the rest of the day will be relatively quiet. Mostly cloudy skies through your Monday won’t make much room for sunshine. We could actually squeeze out a few more showers during the afternoon/evening.

Any rain that does fall won’t cause much of a problem. Cooler air wraps in during the afternoon from the northwest so we’ll see some cooling, rather than warming, north of highway 20 after midday. Highs for the southern half of the area will reach the mid to upper 60s.

That cooler air takes hold by tonight. Lows fall into the 30s. We’ll start Tuesday with clouds but they don’t stick around very long. By the afternoon, we should have sunshine to close out Tuesday. Rain chances return late Wednesday night and continue Thursday and Friday. Storms are possible on Saturday. Easter Sunday looks dry with highs in the upper 60s.

Severe Weather Risk Sunday

There is still some uncertainty about storm potential later today. We’ll have most of the pieces of place but one crucial ingredient (instability) may be out of the mix. We’ll have to watch through the day to see if things change. The storm potential is there but the question is whether or not it will hold together and reach eastern Iowa. If we do see any severe storms later this evening, the main concerns continue to be damaging winds and hail.

Strong south winds transport warm air to our area again today so some areas could see temperatures closer to 80° like we had for Saturday. But with warm air comes higher humidity potential. Sunday may feel slightly humid. Once storms move out early Monday morning, rain is possible through tomorrow. Breezy south winds become northerly and cooler air begins to move in for Monday evening.
