high risk Posted February 28, 2017 Share Posted February 28, 2017 5 minutes ago, yoda said: (FYI: This is from the Lakes/Ohio Valley severe thread) Never seen this model run before... going to watch it to see what it does as it updates later today It's a HRRR time-lagged ensemble, where they take the previous (I believe) 3 HRRR runs and make means and probabilities from them. Not sure exactly what defines a tornado occurring in the post processing here, but it's likely something tied in to updraft helicity. Link to comment Share on other sites More sharing options...
BlizzardNole Posted February 28, 2017 Share Posted February 28, 2017 Looks like the line could be passing through NW MontCo just as I get off the MARC train. That happened with a nasty storm last summer -- I felt like I was in a washing machine for the 50-yard sprint to the car. Umbrella was no help as it was raining sideways; and a bolt hit real close by just before I got to the car. I have never been so soaked LOL!

Scraff Posted February 28, 2017 Share Posted February 28, 2017 This thread is way more fun than the long range pray for snow thread. LOL. Instead of my typical hibernation, I'm all in for severe. So we have a legit tornado threat brewing tomorrow (or potentially anyway)? Link to comment Share on other sites More sharing options...

And yes I did mean 1pm We are going to have clouds - I don't think anybody is questioning that - but the thickness and coverage is what is in question.

Eskimo Joe Posted February 28, 2017 Share Posted February 28, 2017 Looks like SPC just went 10% hatched close to Chicago (don't agree - lake breeze will probably kick in and kill that threat), and MOD risk for parts of MO, IL. Link to comment Share on other sites More sharing options...
yoda Posted February 28, 2017 Share Posted February 28, 2017 MOD risk appears in 1630 OTLK... large hatched 10% with small area of 15%... hail probs increased to 45% hatched... this leads me to believe we will likely be in the ENH risk in the 1730 Day 2 OTLK Link to comment Share on other sites More sharing options...

Not saying we wont' get nudged to ENH but just saying I'm not entirely certain the two are linked. Link to comment Share on other sites More sharing options...

I'll be perfectly satisfied with it waiting until after 4:30, which is when I get off my VRE train. Last year, I got stuck for about 45 minutes at the station before mine due to a tornado warning out near Manassas. Once the warning was lifted, we continued on our merry way, only to get rocked about halfway between the stops. That was fun! Link to comment Share on other sites More sharing options...

Synoptic gradient looks strong enough to keep lake breeze at bay. Bigger question/issue is getting enough instability that far north, hence the better probabilities down around I-80.

Eskimo Joe Posted February 28, 2017 Share Posted February 28, 2017 We stay in the Day 2 slight per SPC. Good move. Quote ...East of the Appalachians from southern New York/New England into the Carolinas and Georgia... Over the northern part of this area, several rounds of strong/severe storms may spread eastward across the region before the threat ends with passage of the cold front. Farther south, the primary convective threat is expected to remain closer to the cold front where a line of storms is likely to develop and progress eastward/southeastward through the afternoon into the overnight hours. Low-level moisture is expected to gradually increase, especially from the Atlantic, with surface dew points of 60-65F from the Delmarva region southward, and 50-60F extending northward into southern parts of New York and New England. The limited moisture will be offset to some extent by an plume of modestly steeper mid-level lapse rates spreading over the area, with MUCAPE of 500-1000 J/kg possible over the area. Strong winds aloft and associated vertical shear will enhance storm organization, with potential for some rotating updrafts and bowing line segments to develop through the night. Damaging wind gusts are expected to be primary severe threat, although a tornado cannot be ruled out given the large clockwise low-level hodograph structure indicated in forecast soundings. ..Weiss.. 02/28/2017 Link to comment Share on other sites More sharing options...

"isolated severe" Could be good for your "surprise on the day of" mentality. I could see tomorrow being pretty mundane with a few isolated severe reports to be honest. I am NOT expecting those sigtor params to be realized by any means. Only rarely do we get two good events in a row...let alone in February/early March. A lot folks buy into parameters too much (myself included). I'm about 30% buying into something more substantial - we bust well... Link to comment Share on other sites More sharing options...

Kmlwx Posted February 28, 2017 Share Posted February 28, 2017 @WxWatcher007 - Your scale might be at odds with itself if Eskimo Joe bites on this one at some point.

The 4k NAM clears us starting around 18z but it's a pretty small pocket centered right over our area. If that pocket does not materialize then we don't get sig severe.
