DAILY BLOG - December 21, 2022

 Good Morning. This is your daily blog and forecast for Wednesday December 21, 2022

One more dry day is on tap for the mid-south before the historic cold airmass plunges into the region tomorrow afternoon. Highs today will be in the 40s everywhere with stubborn cloud cover being present all day long. Can't completely a couple peeks of sun for the very lucky folks! Tonight, there is some chance for some pre-frontal showers to develop. Not yet sold on this idea, but will monitor the trends throughout the day and make forecast changes as needed. 

** First Alert Weather Day Thursday Through Monday **

The big story for this forecast will be the historic cold that is expected to plunge through the area tomorrow afternoon and tomorrow night. The National Weather Service has issued a Wind Chill Warning for the entire area for tomorrow night and Friday. Wind chills are expected to drop a mere 40+ degrees in a 3-6 hour timeframe! As the front moves through, expect rain to change quickly over to snow. The last several model runs have increased snow totals over the area. Given how quickly this system will be moving, I am not ready to increase my forecast totals just yet. Instead will continue to advertise 1-4 inches of snow North of I-40, and a dusting to an inch south of I-40. This forecast may need to be adjusted if forecast models continue to increase totals. 

The cold airmass will hang around for several days before retreating on Monday. Interestingly, models try to develop a clipper system that may bring the area a second shot at some wintry weather. There is still significant disagreement amongst the various models, so will continue to monitor this. 


CONFIDENCE: 

High confidence on all elements.

Daily Blog and Forecast Discussion - March 1st

 Daily Blog and Forecast Discussion Brady's Weather Page 3:03 pm CST March 1, 2023 *** FIRST ALERT WEATHER DAY *** Bottom Line up front: Everybody should have multiple ways of receiving warnings over the next 24-30 hours. Everybody should also know their severe weather safety plan, and enact that plan when warnings are issued.  SHORT TERM :  Currently, a few light rain showers are being observed over portions of Tipton County Tennessee at this hour, but other than that, conditions are clear, calm and quiet for now. Temperatures are in the low to mid 70s everywhere, with dewpoints in the mid 60s. It feels like a severe weather day around the mid south. The Storm Prediction center has placed an enhanced risk of severe weather across the southern half of West Tennessee, and a slight risk everywhere else. A lot of moisture, high CAPE, and decent height falls will probably contribute to some severe storms across the area. All modes of severe will be possible with hail and win...

DAILY BLOG - Discussion for December 22, 2022

 This is your daily forecast for December 22, 202 🚨  Dangerous weather expected for the mid south this afternoon. Be prepared for rapidly changing weather conditions  🚨 Currently, radar is showing some light rain or flurries around West Tennessee and Eastern Arkansas. This may not be making it all the way to the surface. This is only an appetizer as to what is coming later today. Currently, temperatures are in the 40s everywhere as expected. The inbound arctic air and snow will be the heavyweight of today's forecast issuance.  Model guidance continues to be in strong agreement with the arrival of the arctic cold front by mid afternoon across the northern sections of the area. Precipitation is expected to develop along the front initially as rain, but will quickly transition to snow as the temperatures plunges. Large scale upper forcing will create quite a bit of lift, especially north of I-40. This creates a very conducive environment to support accumulating snowfa...

Daily Blog and Forecast Discussion -- March 2, 2023

Daily Blog and Forecast Discussion Brady's Weather Page 3:18 pm CST Thursday March 2, 2023 SHORT TERM (Tonight through Friday night) Go Outside. Enjoy this nice weather while you can. In just a few short hours... It won't be like this, not until Saturday morning anyway. It would be an understatement to say that we are in the "Calm before the storm"...and that's quite literally. We have a smorgasbord of weather in the short term so let's dive in.  Let's start with tonight: As I type this, an already intense closed low system has dug into northern Mexico. This system will eject northeastward over the next few hours, and it is does, It is going to bring a severe weather outbreak to portions of Texas, Arkansas, and Louisiana. It's going to be a long night for them. As for us, we are also in for a long night, as a warm front is going to lift north through the region. Storms are expected to develop along this warm front and some of them could become severe w...
