Euro EPS had a nice overrunning for TN/NC and the SLP is getting closer to the coast, still 150 miles or so off the coast but it does get precip up and down the east coast for coastal areas. Still 6+ days out, looks like central NC is a little to warm. This is all for 3/1 potential. The 3/3 potential is still there. Very active southern stream next 2 weeks, cold is around, well March type cold, would hope one of these hits western NC.

 

Thanks.  Looks like each day the models will improve one of the potential storms a bit while the others get worse.  They don't know which to amplify because of the fast flow.  I'm a little surprised that the Euro is swinging so wildly with the southern stream.  It was so locked in on the last storm.

Blacksburg is amazing at times. How is a forecast like this possible

 

  • TuesdayA slight chance of snow before 10am, then a slight chance of rain. Mostly cloudy, with a high near 55. Calm wind becoming southwest around 6 mph in the afternoon. Chance of precipitation is 20%.
  • Tuesday NightA chance of snow before 8pm, then a chance of rain between 8pm and 4am, then a chance of rain and snow showers after 4am. Cloudy, with a low around 34. Chance of precipitation is 40%.
  • WednesdayA chance of rain and snow showers before 1pm, then a slight chance of rain showers between 1pm and 5pm, then a slight chance of rain and snow showers after 5pm. Partly sunny, with a high near 43. Chance of precipitation is 40%.

Robert hasn't posted anything about this pattern lately. The other day he was pretty excited about it. Model watching days are getting very limited it seems.

Yeah, seems like everyone got lured in to this super cold outbreak that was showing up a few days ago (widespread teen lows in NC) and such and now highs through next weekend are in the low to mid 50s! Not going to get winter storms like that!

Well it does get cold Thursday-Friday, but we get precip Wed and Saturday.  Then it gets cold again Sunday but we get precip on Monday.  :bag:  

 

Also, we are +10F  warmer on average than mid-Jan, so below is low in 20F's for end of Feb which would have been in the low teens in mid-Jan.

GFS ensemble has 38 high 24 low for RDU on Sunday. There's also a possibility of 5 nights in a row below freezing for lows. 00z Euro is too warm at 2m for this time period, control AND ensemble is below freezing into March for lows. Op Euro still showing 17 degrees in RDU. Like I said in the pattern thread, Euro hasn't figured out the cold yet, and I don't think any model has really. GFS has consitently shown sub freezing temps from 2/1 on and all of a sudden 06z it spits out 40s? It's the GFS. OP Euro isn't even that warm for minimums and like I said, too warm compared to ensembles. Food for thought. Don't let one or two runs of the models get you to cancel the cold. Although it's not going to be a crazy cold outbreak it's not going to be warm...lol at the ridge popping up at on the models though. Texas good get it all. I'm kinda done model watching.

 

edit: I wrote this before really looking at 500mb maps, etc. Most models pop that SE ridge quick, so whatever cold we do get, it's short lived...so this one has about a 0.1% chance of perfect timing + adequate cold (and saturation) + adequate track. On to the next one.

Let's just hope it's not like last March, cool and rainy. Although March is usually a wet month, let's hope for atleast seasonal temps.

The 12z Euro looks cold enough for N NC for snow on 2/26. but most of the precip misses the area to the south and BL temperatures appear to suck (if there was more precip, that may not be the case, though).

 

The 00z GGEM is easily cold enough for 2/26, but most precip misses N NC to the north.

 

Blend them and profit.  :weenie:

 

For 3/1, the GGEM brings the low down over S FL and out to sea.  We've got that one right where we want it at this point.  LMAO.  (Not really)  The surface low passing over Lake Okeechobee is a benchmark track.  :huh:

3/1 on the Euro turned in a nice MA to NE coastal snow event.  You knew it was a matter of time, suppression was a never a concern, I bet this turns in a bigger event, the NC mountains have a chance with this though.

 

Bring on spring!

He has an excellent writeup this morning, fresh off the presses.  You have to be a paid subscriber, but it outlines his thoughts.  Generally speaking, there are still lots of question marks with each of the next several systems.  We need to wait on the midweek system to get out of the way before the 3/1 system will become clearer.  We need the 3/1 system to get out of the way before the following system will become clearer.  His specific thoughts on the whole thing are quite enlightening.

I don't understand the science behind always waiting for the first system to get out of the way before the models can understand the second. It isn't like their equations get blinded by a system in front of another system. There's always a system in front of the system you're watching, somewhere.

There must be something to it though because you always hear about it.

Just a matter of time before Daytona gets a storm... on the door step

 

It's going to be close.  That cell is going to fringe Daytona Beach.  If the speedway was on the south side of town, it would probably escape unscathed, but alas...

 

Luckily, the main band of storms is to the north for now.  This isolated one shouldn't last long if it hits.

It doesn't make sense at all! I agree! I think it's a coping mechanism. The one we track for a few days, fizzles or rains or goes poof, then suddenly a storm appears behind it with possibilities, so we blame the first one, and look for the second to produce/ make us feel better!?

Looks like the rain is setting in. It will take at least an hour to dry the track so I really don't like the looks. Short range models seem to keep it coming south some too so it could be a long night for race lovers.

The race sucks until 25 to go, too.  Restrictor plate races FTL. 

 

And rain...  :axe:

Yeah, I see they finally started talking about the rain. That cell looks to be building south. There is lightening well south of the main line out west of the track. I wonder if that is a precursor to storms devolving farther south?
