Tuesday Thunderstorms - Severe Potential


Monday AM Update:
This morning's look at the risk area from the Storm Pediction Center is still pretty close to what we've been seeing the past couple of days. Kentucky and Tennessee are included in the ENHANCED risk and everyone in the Local 6 area is covered under the SLIGHT risk area. To see how each risk area is defined, see the Sunday PM Update below. 


Sunday PM Update:
The Storm Prediction Center has updates their outlook and it still places KY/TN in the area for greatest risk for severe storms on Tuesday. A few showers and storms will be possible late tonight and early tomorrow as an initial weak front passes through the area. By Monday evening, a warm front will lift back north across the Local 6 area, bringing back the moisture needed for Tuesday storm development. 
Here is a closer look at timing of the main line of storms expected on Tuesday:

Friday PM Update: 
All signs have pointed to a major storm system developing in the heart of the central plains on Monday, moving east on Tuesday to bring the threat of strong/severe storms to the Local 6.
Since early this week, computer models have indicated the development of this storm system and the threat of severe weather associated with it. Over time the risk area has been more defined to include the Mid-Mississippi  and Tennessee Valleys. 
An initial chance of rain will arrive Sunday into Sunday night as a warm front lifts north across the Local 6 area. A weak front will pass through early Monday bringing a brief period of cooler, drier air. Another warm front will lift back north across the region late Monday night and early Tuesday allowing warmth and moisture to return to set the stage for the larger storm system. The timing of storm development will coincide with the heating of the day and any sunshine that might break through will further destabilize the atmosphere in Kentucky and Tennessee leading to the highlighted risk area above. 
Damaging winds will be the greatest concern with storms that move across the area. There will also be a threat of isolated tornadoes, particularly as storms begin to develop Tuesday afternoon. 
Of course this storm system is still several days away so timing may change a little but I wanted to give you a heads up going into the weekend. Updates will be forthcoming over the weekend and we'll see if a Weather Authority Alert Day will be necessary.
Our area is typically a target for organized lines of storms that bring embedded weak tornadoes and damaging winds. Here is a look at the average number of times we see these types of events during the cold season, each decade:

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...

Strong El Nino Impacts for Winter in the Mid-South

Wednesday September 9, 2015 Update: Created by Jennifer Rukavina via NOAA/ESRL Data The current trend will continue as NOAA continues to forecast a strong El Nino episode through late Winter and possibly Spring 2016. The following two graphics show on a map what I have detailed below about "Notable El Nino Episodes for Winter". Winters tend to be warmer than normal and precipitation stays fairly average. The two maps compare the previously mentioned winter El Nino episodes to the long-term average from 1950-2007. Created by Jennifer Rukavina via NOAA/ESRL Data August 21, 2015 Original Post Forecasting into the season ahead is most accurate when looking to similar weather patterns of the past. As you have probably seen in the news El Nino is expected to strengthen into the upcoming fall and winter. I've done a little digging into the historical record to find out how we have fared during similar El Nino episodes. Here is what I was able to fin...
