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.

Record Watch Continues Through Wednesday

Dry and unseasonably mild weather returns for the next couple of days before BIG changes later this week. Highs today and tomorrow near (and possibly pass) record high temperatures across the board. The combination of sunny skies and southwesterly winds propel us to the low 60s in the north and upper 60s farther south.

Fog is possible again tonight, with lows into the 40s for most of the area. Wednesday turns out quite similarly to today with one minor difference…a few degrees warmer. Highs tomorrow reach the mid-60s to low 70s. A cold front Wednesday into Thursday begins to drag us back to reality. By Thursday, we only warm to the mid-40s. A few showers track in during the afternoon on Thursday.

Light snow mixes in with rain on Friday with much stronger winds. Light snow is possible Saturday morning and again briefly on Sunday.

Record Highs Broken Today

Cedar Rapids broke a 36 year record of 60° set in 1981. Iowa City broke a 33 year record high of 63° set 1983. Moline broke an 87 year record of 65° set in 1930.

Tomorrow will be another potentially record breaking day across eastern Iowa with plenty of sunshine and southerly winds.

TRACKING: Warm Monday with Rain & Storm Chances/Winter’s Return

We’ve got quite a bit of different weather coming at us in the next seven days.  First off, I hope you were able to enjoy the record-breaking temperatures this weekend.  Here are the record highs from Sunday.

Tonight, clouds increase ahead of our next storm system.  Patchy areas of fog are possible with lows dropping into the upper 40s and lower 50s, with a SE wind 5-15 mph.

Moisture increases across the region on Monday, leading to off and on showers and even a few thunderstorms during the day, as the center of the storm system tracks to the north.  Highs will still be warm in the upper 50s to middle 60s (records in jeopardy once again).  Winds will be S 10-20 mph.  Generally 0.25″ to 0.50″ of rain out of this system.  We will watch area rivers and streams for rises due to runoff.

Tuesday and Wednesday will be nice days, with once again record-breaking high temperature potential.

 

 

  RECORD HIGHS
Feb. Waterloo Dubuque Cedar Rapids Iowa City
21 65 (1930) 63 (1930) 68 (1930) 69 (1930)
22 61 (1984) 61 (1985) 64 (1984) 63 (1922)


We begin cooling down on Thursday, with a chance for rain in the afternoon.  This is part of a strong storm system that will track very close to eastern Iowa, bringing a lot of wind, rain, wintry mix, and snow as we head late Thursday night into Friday.  This will bring cooler temperatures back to the region next weekend.

Still too early for details, but stay with KWWL Storm Track 7 for updates.

TRACKING: Warm Temperatures/Monday Rain Chances/Back To Winter

No doubt about it, we have had a stretch of unseasonable warm temperatures.  A handful of temperatures record were broken across the region Saturday.

Locally, the records in Waterloo and Cedar Rapids fell just a few degrees short.

Another warm day is on tap for Sunday.  In fact, record highs across eastern Iowa are once again in jeopardy.

Enjoy Sunday, as it will be a mostly sunny day.  The warmth will continue into Monday, but we are tracking a chance for rain.  A low pressure system in the plains is going to draw in an abnormal amount of moisture into eastern Iowa.  Showers and even a few thunderstorms are possible during the day on Monday.  Another round is possible late Monday afternoon into the evening, before ending overnight.  When all is said and done, 0.25″ to 0.50″ of rain is possible, with locally higher amounts possible.

Beyond Monday, temperatures remain above average, but on a slight downhill turn.  We continue to track a potent storm system for the end of the week, that looks to bring rain, wind and even the chance for snow returns.  Stay tuned…

Unseasonably Warm February Temperatures

It felt more like May than February today.

It’s no secret this month has been warm.  Several daily high temperature records for February 17th were broken across the state of Iowa.

It’s not often that it reaches 70° in February across eastern Iowa.  Here are the number of times it’s reached 70°+ (including today) in the big four, as well as the all time record high temperature for February on record.

 

We also found that Washington has reached 70° or warmer 7 times during February since 1921.  That number is now up to 8 as of today.

Another interesting fact about today…the difference between the low in the morning, and high during the day.  The difference for today all made the top ten in the big four.

Record Rainfall This Morning

Earlier this morning, a few showers and even fewer thunderstorms tracked through the area. During that time, Dubuque received almost an inch of rain – breaking a 136-year record.

Most of the area stayed dry overnight. Only a narrow band of rain fell from Williamsburg north east through Dubuque.

ICYMI Nov 17- Earth from Mars/ Earthquake Aftermath/ Records/ Lightning

As you may recall, a powerful 7.8 magnitude earthquake struck New Zealand, killing two people.  Scientists say that because of the quake, the seabed lifted nearly two meters (6 feet) in the city of Kaikoura of South Island.  Read more here, and see aerial shots of New Zealand before and after the earthquake.

Today might be the last day we see high temperatures like this again for awhile. Cedar Rapids and Iowa City tied the record. Des Moines reached 76 degrees (previous record 75 1941).
