Arctic Blast Round 2, Wintry Mix Possible This Weekend

Click to enlarge
We've finally emerged from the coldest air we've see this season as temperatures warm closer to and just above freezing on Wednesday but it's only a lull. An area of high pressure over Eastern Canada will allow cold air to spill back down in to the Midsouth and Upper Midwest but for a shorter period of time than the last round. This blast of arctic air is headed our way Wednesday night only to be followed by a possible light wintry mix by the weekend.

Computer models are not in good agreement about the timing of any moisture arriving to the region but if it arrives early Sunday, there is a good chance that freezing rain and sleet will mix with rain for the onset before switching over to all rain. That scenario will become more clear and we get closer to the weekend. In either case, temperatures will warm quite a bit into the 40's Sunday-Monday. You can identify the warming trend on the Looking Ahead graphic to the left.
Near record cold snaps are not uncommon this time of year and we are getting pretty close to the time of year we see the average coldest days for the Paducah area. The map below indicates that occurrence between January 11-15th.

Planting Zones Heading North

As our global climate changes, so does our planting zones, helping us determine which flowers/shrubs/trees are hardy in specific areas. The Local 6 area has always been split by 2-3 growing zones so placement becomes very important to those in the agricultural community. The image below represents the average over the past 30 years. Climate Central published the following information:  "What kinds of flowers, shrubs and trees you’ll find at your local nursery depends on your climate — how warm it tends to get in summer, and how cold in winter. A plant that’s happy in Wisconsin might be miserable in Alabama, and vice versa. The U.S. Department of Agriculture has formalized these differences into " hardiness zones " — strips of similar climate that run more or less east-to-west (except in the high mountains), where particular plants should do especially well. But as the planet warms under its thickening blanket of greenhouse gases, those zones are shifting northward. Th...

Round 3 on deck and wrap-up of snow depth thus far

Snow Depth as of December 30, 2012 with additional snow expected New Years Eve night. (Reports from viewers) It is becoming quite clear where the jet stream has set up for the start of winter. People in Southern Illinois and neighboring MO counties along the Mississippi River can barely keep the roads clear while everyone south of the Ohio River is wondering if we'll ever see snow this winter! :) New Year's Eve night is when we are expecting another (although light) snow event across the same areas where you see higher snow depths above. A WINTER WEATHER ADVISORY begins Monday at Noon and continues through Tuesday at 6AM for most of Southern Illinois and SEMO. The latest advisory map is below.  Winter Weather Advisory - Paducah/St. Louis National Weather Service Snow totals are not expected to be significant but with icy snow pack across much of the advisory area, any additional snow/sleet may make for hazardous conditions again for New Year's Eve night and New...
