Early Sunday Afternoon Weather Update

December 21, 2014

We have been forecasting a storm for the Midwest since last week. We had mentioned Thursday the chance of any accumulating snow in eastern Iowa is low and if there was any it would be light. That is still true as of today. Here is the latest snow forecast for Iowa and the surrounding states from the NWS in La Crosse, WI.

Weather Extra Bar

A cloudy sky has been common around here lately and I don’t expect the clouds to clear any time soon. Temperatures will slowly warm to the mid-upper 30s Saturday through Monday. It turns colder by the end of the year and the first few days of 2015 as temperatures are expected to be below normal.

We are tracking a low pressure system located off the northwest coast (south of Alaska) Friday afternoon.

It is forecast to move across the Midwest and bring rain and snow chances Monday and Tuesday to Iowa. That is what we do know. The details on the storm are what are unknown at this time. The amount of moisture in the storm is about 0.30” and some of this will fall as rain therefore minimizing the amount of snow possible at this point. This has been pretty consistent for the last couple of days.

All model guidance, from update to update for the last few days, has not been consistent….that is not helpful when trying to make a forecast. Once the storm moves onshore along the west coast the weather balloons will be able to get more information from the storm. This should help the models get a better handle on the situation.

As of this evening, if you have any travel plans in eastern Iowa this is how I see it.

Keep in mind their might be some adjustments to this storm. So if weather is going to impact you early next week stay updated on the forecast.

NORAD’s Santa Tracker Began With A Typo

December 19, 2014

NORAD Santa Tracker

 

Here is part of the story from NPR:

Terri remembers her dad had two phones on his desk, including a red one. “Only a four-star general at the Pentagon and my dad had the number,” she says.

“This was the ’50s, this was the Cold War, and he would have been the first one to know if there was an attack on the United States,” Rick says.

The red phone rang one day in December 1955, and Shoup answered it, Pam says. “And then there was a small voice that just asked, ‘Is this Santa Claus?’ “

The sky will remain cloudy tonight with no wind and temperatures dropping into the teens by Friday morning. The sky will be mostly cloudy to cloudy through Thursday next week. A few rays of sunshine are possible Friday and Saturday.

A few light snow showers are possible Tuesday as temperatures drop behind the low. Flurries may linger into Wednesday. A gusty northwest wind is expected Tuesday and Wednesday. Cold air, with highs in the 20s, return Wednesday and will continue for the rest of the year.

Christmas Snow?

December 17, 2014

Will it be a white Christmas or not?

While it’s too early to tell, we’ve been hearing from several of you that you’re hearing of an erroneous forecast floating around for that day.

Model guidance confidence level, at best, is average Sunday through Thursday. There are many unknowns at this time — like timing, position of the low, strength, position of the fronts and much more. Early indication shows light snow if any. We will see how the week plays out. That is why there is a 20% chance of snow Tuesday and Wednesday.

There is no point in hyping something that is not necessary to do that far out in time.

Not much moisture, (less than 0.25″) through Wed eve. This is combined with rain & snow chances Mon-Wed.

Here is look back at the last 119 years.

Here is the historical probability of a white Christmas (1″ of snow on the ground).
