MORE WINTRY WEATHER ON THE WAY...

January 20, 2020

Before I get to the wintry weather ahead, I just wanted to mention that I have 2 spots still available for weather school this Saturday. My guest presenters, (TV meteorologists Rebecca Kopelman and Nick Stewart) and I had a meeting over the weekend to go over content and I was super pleased with what we have to offer. Some very compelling sessions on major weather events that have impacted the Midwest (and the nation such as the Joplin tornado and the super tornado outbreak of 2011 in Alabama...awesome videos included).

 

We also have sessions on long term, medium, and short range forecasting We'll show you how to find the data online and work with you to break it down, perform analysis, and prepare your own forecasts. You'll get down and dirty and deep into the world of forecasting. Over 43 years I've seen some things and learned a thing or two. We also have a nice session on teleconnections and analogs which is the wave of the future in long range forecasting. It's 5 hours of fun and fraternization that we are really looking forward to. Very personal, hands on, and interactive!

 

If you would like more information please contact Carolyn for the specifics. A lunch is included. Would love to have you join us this Saturday at noon!

 

MORE SNOW LIKELY LATER THIS WEEK...

 

Another wintry weather system looks to impact the area starting mid-week. it will have 2 phase. The first arrives Wednesday, after a lull later Wednesday night early Thursday it's followed by part 2 later Thursday into Friday/Friday night. It could be a prolonged event.

 

Important to note, this system will be much different than the system that impacted the region last weekend! There are two major reasons why... 1.) Temperatures. On average, temperatures for this system will likely hover in the upper 20s to lower 30s. This means that precipitation could have a rain/snow mix tied with it... especially Wednesday in the south. In fact, some locations south of I-80 could even get into some very light rain for a short period of time... 2.) Wind speeds. On average, wind speeds through much of this event will likely be near the 5 to 15 mph range. (This is in stark contrast to the previous event that had winds well over 30 mph throughout.) Therefore, visibility reductions will be more in the 1 to 3 mile range.

 

At this time, the primary impacts are expected to come from snow accumulations leading to snow-covered and slippery surfaces, primarily untreated surfaces. Snow amounts are still subject to change as temperatures are going to be very touchy...a couple degrees could impact totals a couple of inches with higher or lower snow ratios. Here's what the morning runs were showing at a 10:1 ratio which I prefer due to the warmer thermal profiles. These are totals for both periods of snow. The first looks lighter in the 1-2" category...3" at the very most. Plenty of time for things to move around so this is just a first blush!
