December/January 2019/20 Winter Speculation Thread
jaxjagman replied to AMZ8990's topic in Tennessee Valley
National Weather Service Nashville TN 207 PM CST Sun Dec 8 2019 .DISCUSSION... It`s fairly breezy this afternoon with quite a bit of cloud cover scattered over the area. The southerly breeze is pulling moisture northward as a broad area of low pressure is organizing over the Rocky Mountain foothills. That is in response of a negatively- tilted longwave trough digging into the western CONUS. Closer to home, a stray shower can`t be ruled out through the rest of the daylight hours as moisture advection continues. The broad area of low pressure will slide east this evening before lifting northeast through the day tomorrow. Models have cut back on the QPF and coverage of shower activity tonight through the first half of Monday. Coverage will increase ahead of frontal passage which will occur Monday night. Behind the cold front, things get interesting. Models are producing quite a bit of post frontal QPF thanks to southwesterly upper flow and a strong jet streak to the north of the area. This will leave Middle Tennessee in the right entrance region of that jet streak Tuesday/Tuesday night. Temperatures will drop through the day on Tuesday and rain will transition to snow with a period of sleet possible in between. Models, besides the Euro, seem bullish with the snow amounts. There`s a couple of reasons for that. Omega in the snow growth region is quite impressive for the Tuesday time frame and frontogenesis is strong due our positioning relative to the jet streak. With any winter weather setup in Middle Tennessee, there are always some potential red flags. First and the most frequent question with post frontal snow events around here is how long will moisture stick around. Model soundings show the low levels beginning to dry out a couple hours after the rain to snow transition. Seeder feeder processes may prolong the snow a couple more hours, but it is something to take note of. Second, it will take some time or decent snowfall rates to get snow to begin to accumulate given warm, wet surfaces. Lastly, if there is a prolonged transition from rain to sleet to snow, that will obviously cut down on snow amounts. All this leads to a low confidence forecast at this time, but we trended toward a slightly snowier forecast. For most of the area, the current forecast is for less than an inch. The northern Plateau and along the Kentucky border could see a little more than an inch. There is plenty that could change over the next 24-48 hours so stay tuned.- 1,666 replies

These last three strong +IOD events have led into at least a moderate to strong LaNina the follwoing year.1995-moderate...1998-strong....2007-strong Few of the seasonals are starting to pick up on a possibly developing LaNina upcoming. The cold pool down into the subsurface continues to shift further eastward,so seems possible right now we are starting to see a developing or Nina conditions in it's early stages
