CHASE
SUMMARY:
For the few days leading up
to this chase day, severe weather was being observed by a system that
the models showed a potential for coming into the Mid-Atlantic Region.
Places like Missouri, Arkansas, Mississippi and Tennessee all had
significant and tornadic weather the day before. While that in itself
is never a precurser for severe weather here in the Mid-Atlantic it did
show potential of this system being modeled and forecasted. The Day 2
from SPC was showing a good potential however and many did feel we
might see tornadoes in this region.
The chase day began early in the morning checking models and SPC for
the latest. One bad sign was when the SPC actually pulled back on the
Moderate Risk, but it was still there nonetheless...as was the Slight
Risk with a 5% broad reaching all the way into the greater DC/Baltimore
Region. Finally, around 10am, the first line was approaching the DC
area, from the north. This was quite early, and get me somewhat
excited. The orientation of the main line of storms did show that there
was plenty of time to get to the southern areas, which is where our
target was. My initial target was Washington, VA, but I quickly
realized by 10am that I'd have to forget about that target in favor of
something further south.
At 10:45am I departed my house to rendevous with Mark Ellinwood where
we made a quick stop in Rockville for a manditory errand and then
quickly moved on down I-270 to I-495 to I-95 southbound. We wanted to
reach Fredericksburg as quick as possible, and get ahead of the leading
edge of the storms that we just fell behind in Rockville. This was a
screamingly fast line, with forward motion around 60mph. Stormcell
motion was SE so forward progression was ~ 50mph. We did manage to get
ahead of the line and finally took a stop near Emporia, Virginia
(14:05) just north of the Virginia & North Carolina border. I
personally was having a hard time seeing what Mark had forecast. My
limited forecast ability and knowledge lets me forecast traditional
set-ups, of which this WINTER storm was not. From Emporia (14:45) we
ventured further south on I-95 into North Carolina and at US 158 near
Roanoke Rapids, felt we were sufficiently south enough and decided to
head west toward the line (14:58). The thought was that with the system
moving eastward at nearly 60mph now, we didn't see need to go far, we
would meet the line of storms halfway. But that didn't happen as we
continued west (out of the most favorable conditions) the line stalled
to the north. Only the western areas were progressing. Now we weren't
sure. It was a debate whether to return east to the better instability,
lift, shear, etc. or wait. We U-turned (15:50) and took US 158 back
west after stopping near Warrenton, NC. Since we had plenty of time
now, we stopped in Roanoke Rapids (16:24) and waited to see what the
trend of the storm line looked like. After the brief 20 minute stop in
Roanoke Rapids we again headed west on US 158 past I-95. Again, we
stopped (17:15) evaluated things, and this time again decide to make a
U-turn in order to get back to I-95 and head south more. Once on I-95
(17:24) south again we continued 20 miles until exiting at route 481
(17:55) and heading east. The line was somewhat catching up now, and we
wanted to dance with the outflow boundary that emerged from the main
line of storms. The hope was still to see new convection from the new
forcing potential now that we were in the area of better dynamics for
storm development (even if marginal). We zig-zagged through local roads
heading south, ahead of the line just waiting for the line to do
something, and it never really did. Around 7:15pm (19:15) when we were
near Farmville, NC we decided that it was as good as it was going to
get and it was time to head home. We looped around Farmville and headed
east (to get back to I-95) right into the advancing line, which wasn't
much. The line never materialized in our area of chasing and our trek
home was a somewhat somber one. However, it was a great road trip and
the first time we ventured into North Carolina for a chase. Being
February, there was no sting to it. If this had been May or June then
I'm sure we would have been upset.
