Hoosier Posted January 9 Author Report Share Posted January 9 All I gotta say is that I hope we don't see a repeat of Lakeshore Drive in GHD in Chicago this Friday. What a debacle that was. Current timing of this one looks eerily similar as far as timing of onset and when conditions may really go downhill. One difference this time is warmer temps which may make some difference in conditions (or maybe not). Of course the world has changed since then with more work from home, but people need to really take this seriously if current models hold.

Hoosier Posted January 9 Author Report Share Posted January 9 2 minutes ago, Money said: 959? Lmao I wish I knew what the Indiana state record low pressure is. Indianapolis recorded 974.6 mb on February 28, 1902, but I'm not sure if that's the state record. If it's not, it's gotta be close. Given the above... quite simply, what the GFS and Euro are modeling would be nearly without precedent, if not without precedent in the historical record. Almost like a poor man's version of the January 1978 blizzard, but weaker and farther west. Quote Link to comment Share on other sites More sharing options...
Hoosier Posted January 9 Author Report Share Posted January 9 Northern Indiana office already talking this up Thereafter focus turns to potential snowpocalypse Fri-Sat. Guidance over the last several days remains pretty consistent with next stupendous pacific wave train disturbance over the Gulf of AK this morning which makes a beeline for the 4 corners by Thu aftn and turns out through the srn plains Fri and into the ern lakes Sat. Surprising good multi-model consensus with both evolution in time and track, taking rapidly deepening sfc reflection from wrn AR Fri morning newd into wrn OH vcnty Sat morning while upper wave goes negatively tilted through the OH valley. Not too dissimilar from current system now but with a colder starting downstream environment and swd displaced sfc low track comparatively and infusion of much needed baroclinicity as arctic air couples to drive an even stronger sys. Deep turn through the srn plains taps into an anonymously moist return moisture plume as delineated in explicit deterministic qpfs Fri-Sat, highlighting the potential for a blockbuster snowstorm for much of the area. However it should be noted proximity of spoiler warm sector east of sfc cyclone which likely albeit short supports a period of mixed precip potential far south and east. Too early yet for specifics other than a generalization for a very impactful storm across the Great Lakes late period, Fri-Sun. 2 Quote Link to comment Share on other sites More sharing options...
Clinton Posted January 9 Report Share Posted January 9 EAXs take this morning Thursday night - Friday: The next storm system will begin to affect the region during this time frame. Initially, it looks like precipitation may develop across Nebraska and northern Kansas as the upper shortwave trough moves into the Four-Corners region. As this wave moves into the Plains, an area of precipitation should develop in the warm advection across southern Missouri and merge with the baroclinic leaf portion of the storm with snow spreading across the entire forecast area Thursday night into Friday morning. Like with the ongoing system, there remains a fair amount of uncertainty with the late week system, both in the potential track and the thermodynamic profile. The ECMWF is farther northwest with the system at this point and this shows in both the probabilities of exceeding 3" snowfall and the probability of having a warm nose affecting southeast portions of the forecast. Both the ECMWF and GFS ensembles show 20%+ probabilities for 850mb temperatures to be at or above freezing at the onset of precipitation. The ECMWF being farther northwest than the GFS. And this once again will likely sit across the KC area adding huge uncertainty to the precipitation type and snowfall amounts. 1 1 Quote Link to comment Share on other sites More sharing options...
