Goodbye Winter Weather And Hello 60s!

SUMMARY: The winter storm came in with cold heavy rain. Early Thursday morning there was a very brief transition to freezing rain. But most of storm, as expected, we saw moderate to heavy sleet. Most locations were done with the precipitation by noon. Measuring sleet is the same as snow and you don't measure sleet as ice accumulation. Now sleet can turn into a layer of ice much like snow can but you still don't measure it as ice accumulation. Here are some totals of sleet around the Valley.

24 HR. TEMP CHANGE: It was very impressive to see such a dramatic change of events within a 24 hour span. At the peak of heating Wednesday we topped off at 77 degrees in Huntsville but this afternoon we were in the 20s. Creating an almost 50 degree difference between Wednesday and Thursday.

1234

FRIDAY THRU THE WEEKEND: Skies will clear out tonight and stay fairly clear through Saturday. On Sunday, we be partly sunny with some high clouds in place. Temperatures will be warming into the 50s for Saturday and Sunday. Hopefully those temperatures will melt whatever is left of the sleet and ice.

Sleet Moving Out, Cold Temperatures Persist

The Winter Storm Warning has now expired for all counties EXCEPT Dekalb and Marshall Cos (continues until 3 P.M.). due to light sleet and flurries that may pass through the Valley and icy conditions on the roadways.

THURSDAY AFTERNOON: The heaviest batches of sleet will push out of the area, allowing for light sleet/flurries to fly during the early afternoon hours. I don't expect any accumulation this afternoon, but the main story will be temperatures staying below the freezing mark. We are not looking to see any of this slush/ice to melt as temperatures will go from the upper 20's to the mid 10's tonight. It's due in part to higher pressure moving in to clear out the skies and cool us down tonight.

FRIDAY & WEEKEND: Higher pressure will settle over the Tennessee Valley, allowing for plenty of sunshine and temperatures to climb into the upper 30's to lower 40's during the afternoon. The weekend will continue to bring in the sunshine and temperatures will rise into the mid to upper 50's due to southerly winds moving back into the Valley.

Freezing Rain/Sleet This Morning Will Impact Travel

doggies

A WINTER STORM WARNING IS ISSUED FOR THE ENTIRE TENNESSEE VALLEY UNTIL 3 P.M. At 6:47 A.M. heavy sleet is falling across the majority of the Tennessee Valley, where only Scottsboro in Jackson, Co. and Fort Payne in Dekalb Co. are still above the freezing mark picking up on a cold rain. Reports of 1.5" of sleet has accumulated in Colbert Co. AL, with 1/4" of inch of ice reported in Athens and Madison, AL. Please avoid the roads if possible. Even thundersleet has been reported due to warmer air trapped in the middle of the atmosphere from the 70's we saw yesterday.

As we head throughout the morning time, Northerly winds will continue to cool surface temperatures down, allowing the entire Tennessee Valley to see sleet during the rush hour commute from 5-11 A.M. As surface temperatures cool, we do have a greater chance of starting to see slick roads during the rush hour commute. Please take it slow on the roadways. Also, be careful of falling ice from trees and powerlines as gusty winds will sweep through the Valley throughout the morning time.

10994166_10206167881541667_8014833509589330088_n

We look to clear out from this strong cold front by noon. Temperatures will still remain below the freezing mark, so continue to be on the lookout for icy roadways, and possible down trees and powerlines from gusty winds.

Our Thoughts On Thursday A.M. Commute

The WAAY 31 Storm Force Weather Team has continuously been tracking the cold front that has threatened to bring significant ice accumulations to the Tennessee Valley. There have been several factors we have been considering that play a big role into predicting ice and snow total maps for the public. **This is also way the Storm Force Weather Team has a policy of posting snow/ice total maps until we are within 24 hours from the start of any winter storm. This cold front proves our point.**

As we've been tracking the timing, amount of moisture, and type of precipitation of this cold front, updated model runs from the GFS, NAM, and European have slowly pushed back the timing of this storm and have slowly dwindled the amount of precipitation behind this cold front. This is good news for the Tennessee Valley!

1) It's keeping warmer air around until 12 A.M.-3 A.M. Thursday morning. Temperatures staying above freezing  for a longer period of time will help keep the ground warmer and delays the change of rain to freezing rain/sleet.

2) This also means with a decrease in wintry precipitation, less ice accumulation is expected. 

In addition, temperatures in the 60's Tuesday and Wednesday, breezy conditions coming in Wednesday night into Thursday morning, and standing warm from scattered showers and thunderstorms coming in on Wednesday will also help slow the process of the ground from freezing over.

doggies

So overall, the WAAY 31 Storm Force Weather Team believes that there will be some slick spots on bridges, overpasses, and higher elevations, but this is not a significant ice accumulation event. Just take it slow on the roadways Thursday morning to avoid slick spots.

Big Changes Coming For Middle Of The Workweek

TUESDAY: It's going to feel like spring outside! A strong flow of southerly wind will take our temperatures from the upper 40's to the mid 60's for highs today! Be on the lookout for patchy fog this morning and misty conditions. By this afternoon, we may see a couple of stray showers with gusty winds and rumbles of thunder due to how warm we will be! Nothing will be severe.

doggies

WEDNESDAY: As southerly winds persist, temperatures will remain in the 60's overnight and into the morning hours as a cold front will begin to approach the Valley. We'll see scattered showers and a couple thunderstorms moving through the area throughout the day. Around 3 P.M.-4P.M., that cold front will slide through the Tennessee Valley, causing the winds to turn from the South to the Northwest and begin to cool us down in temperatures.

viewer1

There is a WINTER STORM WATCH ISSUED FOR LAWRENCE, GILES, and WAYNE Co. TN until 12 P.M. THURSDAY. With this cool down, by 9-10 P.M. We'll start to see a change from rain into sleet/freezing rain by 2 A.M.-7 A.M. and then turn to light snow/flurries by 7 A.M.

10994166_10206167881541667_8014833509589330088_n

As this system comes in from the Northwest, the Shoals, along with Wayne, Lawrence, and Giles counties have the best chance of picking up on possible ice accumulations of .1" and a dusting of snow to 1/2" in the higher terrain of our Southern Tennessee Counties. However, I think that most areas in the lower elevations of Northern Alabama will stay to warm at the ground level to allow ice to accumulate.

From 60s To Teens Along With Some Winter Weather

TUESDAY: A warm front will move through early and as the front passes we could see a few non-severe storms. Showers will be periodic between Monday night and Tuesday night. Temperatures will be warming well into the 60s.

WEDNESDAY: Temperatures will start off very warm in the 60s. A cold front will move through early on and drop temperatures quickly. Even by 3 p.m. temperatures will be around 40. Precipitation types will go from rain to freezing rain to sleet to snow. Although the main precipitation types will be freezing rain or sleet. As of right now only three counties in Tennessee are under the Winter Storm Watch. Be aware that more counties will be included in this over the next 12-18 hours.122341231234

As policy the Storm Force 31 team will release expected snow/ice totals approximately 24 hours away from the onset of the winter weather. We know there will be other winter totals floating around but our stance is to give you information that is most accurate with ample time to prepare.

A Strong Cold Front Will Bring Wintry Weather To The Valley

WINTER STORM WATCH: The National Weather Service has issued a winter storm watch for Wayne, Lawrence and Giles Counties in Tennessee. The timing will be Wednesday at noon until Thursday at noon. Do not be surprised if within the next 12-18 hours more counties are added to this.

12

A strong cold front will be moving across the Valley Wednesday dropping temperatures from the 60s to the 20s. As temperatures drop we will go from rain to freezing rain Wednesday afternoon/evening. We will then change from freezing rain to sleet for the majority of Wednesday night. As the system exits we will be cold enough for snow. Depending on how long it takes for the system to exit will determine how far SE across the Valley the chances for snow will go.

As per Storm Force 31 policy we will issue snow/ice totals approximately 24 hours out from the beginning of the winter precipitation. That will give you more accurate information along with giving the public time to make any plans.

Warm Springlike Start Followed By Winter Returning

RAINY START TO WEEK: As we head into the beginning of the workweek, isolated rain showers and low lying clouds will continue to move across the Tennessee Valley along with warmer conditions as temperatures will go from the lower 50's on Monday to upper 60's on Wednesday. We may hear a few rumbles Tuesday and Wednesday, but nothing will be severe.

WEDNESDAY NIGHT-THURSDAY WOES:  A cold front will sweep across the Tennessee Valley late Wednesday night into early Thursday morning, where isolated rain showers could turn into possible sleet/snow mix starting late Wednesday night into the Shoals and Giles, Lawrence and Wayne Co. Tennessee, to early Thursday morning for East of I-65. Travel conditions could become hazardous throughout this period.

VIDEO: Redstone Closed but some gates remain open

Redstone Arsenal remains closed Thursday due to the large amount of snow on the roadways. Despite the closure essential personnel are still required to report to work. If you are unsure or have any questions you are asked to contact your supervisor.

Redstone's Operations Center is preparing for whatever Old Man Winter is about to throw at us

With wintry precipitation in the forecast for Sunday night and Monday morning the possibility of icy roadways is already on the minds of many.

AMCOM takes responsibility for the boom heard throughout Huntsville Wednesday night

The testing booms from Redstone Arsenal did more than just startle people Wednesday night; they also reportedly did quite a bit of damage.
