A GLAZE OF ICE...
A MESSAGE FROM TSWAILS
Dear weather friends, I'm asking for your help to raise funds for the time I invest in this site and its operational costs. So far it's been a struggle and donations are 50 percent less than at this point last year. I realize times are tough, and we are all feeling the pinch. That's a big reason why this is a no pay site. Many of you are daily visitors and make financial or personal decisions based on the information presented. The majority of you appreciate the honesty, accuracy, and knowledge that you gain. If you fall into any of those categories, I ask that you make a $20 dollar investment in what I feel is a unique and reliable product. That way, we can keep things rolling as they have for more than 12 years. The future is in your hands, and I hugely appreciate the generosity of those who have contributed. So again, if you find value in the site and see the effort that's put into it, please consider a minimal donation to support TSwails today. Thanks for your time and loyalty, TS
SOME SLICK SPOTS...
If you haven't noticed, (especially down south of I-80), it feels a lot more like February today. Temperatures which were up around 60 yesterday have crashed into the upper 20s. At noon, readings were 25–27 degrees colder across my southern counties with enough wind chill to make it "feel" more like 35 degrees lower.
This fresh push of cold air has reached as far south as it's going to and by Wednesday warm air advection is already underway. What that mean is warm moist air will ride up and over the cold dense air at the surface. This process of upglide, will create enough lift to provide some minor precipitation in the form of light freezing rain and drizzle. The north could see some snow or sleet mixed. This begins in the south later in the afternoon and spreads into the north Wednesday evening. Amounts won't be much, generally less than .05", but that would be just enough to create some slick spots. At this time, the NWS has not issued any advisories locally, but that's subject to developments, they could still push them later today or tonight. They have been posted in Missouri and WC Illinois for late tonight and Wednesday.
Here's what the EURO and HRRR indicate for potential amounts of ice, again starting Wednesday afternoon in the south spreading into the north during the evening.
The EURO
The HRRR
This is the EURO surface depiction showing precipitation types Wednesday evening. I do want to stress, most of this is quite light and in some cases nothing more than drizzle. Just enough to be problematic.
There are other issues to contend with later next week regarding colder weather and potentially snow. I will address them in my next post. Models are struggling with the evolution and timing of the pattern, and that will give me some extra time to get a handle on recent trends and developments. That is a wrap for now. Roll weather and if you can spare a donation, I will see to it that it's money well spent....TS
