This output from the European says it all. The map is valid for Wednesday night of next week:



That is a 1042 mb high over eastern Nebraska. This continues to confirm our forecast of highs only in the 30s next week!

Hey Michael , the 850 millibar chart is approximatly 5000 ft. above sea level... The 850 model prog is a lower troposphere prog that can be used to forecast thermal advection, upslope/downslope wind, cyclogenesis and dynamic lifting or sinking due to WAA and CAA.In the cool season, an important 850 temperature is the zero degree isotherm. If the temperature at 850 is above freezing (especially if more than 2 C above freezing), precipitation is likely to NOT fall as snow according to that forecast model. Freezing temperatures at 850 mb can support snow or some other form of frozen precipitation. Sleet or freezing rain at the surface can occur when the 850 mb temperature is above freezing.

Well that is the class on the 850 mb chart for today.. Tomorrow we will dig into the 1000 mb chart and surface charts and try and tie them all together...

Hey Dawn, for severe weather like we had Monday, the temp. needs to be about 70'+, and Dew Point (very important) about 63 or so +. Plus, alot of other ingredients to come about. With temps. in low 60s, if that occurs, you could get just severe t'storms. Usually higher winds,large hail, lightning, probably no tornados. Guys if I'm mistaken let me know on this. This is my general assumption.

John thanks for the info. I feel much better. I don't know a whole lot about weather just that i am terrified of tornadoes. I am ready for the first day of winter to get here(sounds like our first taste of winter will be here next week LOL). I sure hope we get some snow this year i cannot remember the last time i had some good ole snow ice cream. I can't even remember what you need to make it LOL. Thanks again and have a good weekend!
