Record Cold

November 17, 2014

It is cold across the nation. The only place “warm” is south Florida. Here are the temperatures as of 7 PM from the Oklahoma Mesonet.

The jet stream is in a large “U” shape or trough and this is allowing the cold air across the nation.

We are dealing with the coldest air of the season so far and it is cold enough to break record cold highs and record lows for November. The first graphic is from today (Nov 17). A record cold high was set in Waterloo. The NWS does not have any record data for Cedar Rapids or Iowa City.

Now tonight temperatures are expected to drop to near zero by morning with wind chills of 10 to 20 below zero. The forecast lows are all new record lows for Tuesday (Nov 18)

Starting out is a deep “temperature hole” it will be hard to get out. High temperatures again will be in the teens with a better chance of both Waterloo and Dubuque breaking the record cold highs for Tuesday (Nov 18)

Blog Graphic 2

Every state in the lower 48 will have a low temperature below freezing Tuesday morning.

First Snow Area Wide

November 13, 2014

1
Clouds will slowly clear tonight with temperatures in some locations dropping into the single digits by morning — and one to two inches of snow is expected on Saturday.

Sunshine returns Friday, but it doesn’t help warm the temperatures up. Afternoon highs only reach the 20s again.

Clouds increase late Friday night.

Light snow develops around midday Saturday, and continues through the afternoon and night before ending around sunrise Sunday.

Snow accumulations area wide will be 1-2″ with an isolated 3″ reports possible.

This would be our first accumulating snow for all of eastern Iowa. The wind will be light with this snow, so blowing snow will not be a concern.

Snow North then Cold

November 9, 2014

Strong low pressure will track through the region over the next few days. The bulk of the moisture will stay to our north, but we will have some rain showers late tonight through Monday in the area, although some snow will mix in over the northern counties. It will all change to snow tomorrow night and linger into Tuesday morning. Snowfall amounts will depend on when the changeover occurs and how much melts first, but the heaviest will be toward the Minnesota border. They will have a couple of inches. Areas along and south of Interstate 80 may not get anything to stick. It will be cold and windy behind the system. Temperatures will be falling on Veterans Day.

Here is a great link for winter weather information. It is also located at the top of the blog…it says “WINTER”.

The low will track east across Iowa.

1

 

All of the moisture from this storm will remain north across Minnesota.

2

Winter Storm Warning and Winter Weather Advisory north of Iowa through Tuesday.

High temperatures through next week will be in the 20s and may continue through the following week as well.

Snow Still in the Forecast

November 8, 2014

The KWWL viewing area has it’s first good chance at some widespread snow next week, followed by VERY cold air streaming in.

The winds will stay breezy this afternoon but will slowly die down as the low pressure system tracks away from us.   Sunday will see warmer temps in advance of a big push of arctic air for next week.  Monday, a strong system will track into the region and we will see a rain/snow mix develop with a transition to light snow into Monday night.  It appears the heaviest snow will fall in Minnesota. There is some uncertainty as to where the snow will accumulate and how much.  There are many variables in play as to how much snow we will end up getting…. the ground temperature is still above freezing, so much of the snow at the beginning of the system will melt. The exact track of the system… if the center of the low moves only 30 miles, it will mean a difference of you getting a couple of inches of snow or only a flurry or light dusting.  The main story will be the Arctic airmass that will be sliding into the region for Veterans Day through the rest of the week. Highs will only be around 30 for those days and lows will dip into the teens.

This is what the National Weather Service in Des Moines is thinking in terms of snowfall, but, once again, this may change depending on where the system goes and how fast it is moving.

DMX Graphic Forecast

Stay tuned for later updates.
