    Some sort of large fire burning in southern Washington County near Sharpsburg.

    Good stuff.

    I've noticed over the years that 500mb jet streaks / vorticity "ribbons" coming in over the western ridge that go over Yellowstone tend to give us good Miller A events. Not anything scientific, just an sign that I look for.

    12z GFS inching towards my "Yellowstone Corridor" favorite spot. Good Stuff.

    I was about to contradict you, but nope, you're right. This is the stats for every January 13th in the last 30 years at DCA. 60% of all Jan 13th's (since 1996) have been at or above 50.

    Gonna get a 30 deg diurnal today somewhere.

    Just saw the 12z GFS and came in to say that whenever you have 3 streams/waves interacting, the results are either explosive or disappointing. And 90% of the time, it's the latter. Stay full-hearted weenies. The overall pattern is good and we're entering peak season.
  8. wxmeddler
    Sure, you could have the low stack stall out just off the coast producing a longer duration storm. In my mind, we would need that southern stream s/w to not eject or get so strung out that it gets folded into the oncoming impulse from the dakota's but I'm not holding my breath on that. But... This is a triple phase setup, so things usually get messy.

    Yeah. We're not really setting ourselves up for tapping as much moisture as we could be for storms this time of year. The unusual part of this pattern is really the ridge over the PacNW. I don't recall seeing a 588dm high over Nor-Cal this time of year. We're just seeing the downstream effects of that which includes cold air intrusions coming straight south from Hudson Bay.

    Regarding the moisture issue: Yeah, that's not going away. The positive tilt of the trough at H7 and H85 ahead (1) of the synoptics getting in line for us is not great for folding the sub-tropical air back up into our area (2). The leading s/w that kicks out from the sub-tropical jet (3) is a kick in the pants.
  11. wxmeddler
    Trust the Synoptics

    In a relative vorticity framework you get positive vorticity by either curvature (around a low) or by a positive change in wind speed to the right of the vector. Vort "lobes" tend to be produced by the curvature in, or in advance of a low, and the "ribbons" tend to be from areas of high wind shear across a horizontal distance. Look at an H5 wind map, then look at at an H5 Rel. Vort map, then flip them back and forth. You'll see it.

    Can't be upset with this at 5 days out. Not worth worrying about about the details (temps, banding, etc) now.
  14. wxmeddler
    Agreed. The tough issue with this potential that can't be changed is the approach of the pacific s/w. Normally, I like the "ribbon" coming through the Yellowstone region in a ESE direction. With the ridge so firmly anchored over Northern California, we're dealing with a wave diving out from the Dakotas to the SSE. But there's more than one way to bake a cake, and this seems to be one of them. Whatever works. lol
  15. wxmeddler
    The s/w coming through the Dakotas is slightly deeper, good sign
  16. wxmeddler
    I'm looking forward to the rain tomorrow.
  17. wxmeddler
    Not a bad place to be a week out.
  18. wxmeddler
    Found this on another forum

    Torch

    I plotted it out graphically. Ouch. N 125 Mean 21.4 Median 21.7 Std. Dev 4.1
  21. wxmeddler
    Assume no snow until overwhelming evidence proves otherwise is my mantra. 60 percent of the time... it works... every-time.
  22. wxmeddler
    Got a sudden and rude awakening by the WEA from my NYE stupor. My guess is that there are going to be many an upset person after that one. Thankfully it didn’t awaken the wife. Patiently awaiting the squall.
  23. wxmeddler
    Up-slope with diving mid-continent polar air masses are putting in the work. Pick the highest latitude / altitude combo.
  24. wxmeddler
    Sugar grain snow? Doesn't look like dendrites.
  25. wxmeddler
    The snow squall on Thursday pre-sunrise looks legit. Might have to set up an alarm for that one.
