Houston area....snow on the way!!
Discussion just came down the line. Northern parts of the Houston viewing area could see an inch or two on the ground with thundersnow possible. Read below.
HAVE DECIDED TO POST A WINTER WEATHER ADVISORY FOR THE
WESTERN/NORTHERN ZONES FOR LATE TONIGHT/SATURDAY. EARLIER MODELS
WERE SHOWING THE WARM LOW LEVELS BEING THE SAVING GRACE FOR ANY
ICE/SNOW ACCUMULATION. HOWEVER...TEMPS HAVE HELD IN THE MID 30S OVER
THE ADVISORY AREA ALL DAY...AND SURFACE OBS SHOW SUBFREEZING
TEMPS/DEWPOINTS JUST TO THE NORTH. THINK AROUND AN INCH OF SNOW WILL
BE POSSIBLE OVER THE NORTHERN TIER OF COUNTIES...WITH MAYBE 2 INCHES
IN A COUPLE OF SPOTS. ALSO CONCERNED ABOUT A FREEZING RAIN THREAT AS
HEAVY PRECIP COULD EASILY COOL THESE AREAS DOWN TO NEAR FREEZING.
THERE IS ALSO A THREAT FOR ELEVATED CONVECTION OVERNIGHT AS VERY
COLD (-20 TO -25C AT 500 MB) MID LEVEL AIR SPREADS OVER SE TX
CREATING STEEP LAPSE RATES. A COUPLE OF CONVECTIVE "BURSTS" OF HEAVY
PRECIP (INCLUDING SNOW) WILL BE POSSIBLE. WILL ADD MENTION OF
THUNDER TO SOUTHERN ZONES. EXPECTING 1/2 TO 1 INCH OF QPF WITH THIS
EVENT. COULD BE ENOUGH TO WORSEN OUR ONGOING RIVER FLOODING PROBLEMS.

wrkh, any convective bursts are capable of dragging down some of that H5 cold air, and areas that get under those COULD easily get a burst of HEAVY SNOW (and maybe with thunder) and drop a quick inch or two ... even if the temperatures remain slightly above FRZ ... it's POSSIBLE that the HGX area MIGHT see snow/wintry precip mix in ... details are obviously sketchy, but it is quite possible that areas just about 20 miles inland actually change over to wintry precip mix ...

Also, notice the thickness schemes on the 18z ETA ... under the closed H5 low, and it also appears that some kind of deformation band (zone) tries to set up NW of the actual low itself ... which COULD result in enhanecd totals (comparably speaking for SE TX) and a prolonged bursting of wintry precip as the heavier bands drag down the colder air from H5

First line of KFDM forecast says "Rain with some sleet and snow possible...."
Possible, SG ... again with convective enhancement, heavy bursting increases your chances of of a mix, or a complete changeover during the heavier precip ...

You can be assured that pics will be taken and posted if it happens. We need more precip first though!! have already had reports earlier in the day of snow(flurries) within 15 miles of where we are. It the heavier precip does come to pass I would not be at all surprised by changeovers in the heavier bands. The warm air is almost nonexistant in our are after never getting above 38 here today. With a cold core coming in(if it does)it is quite possible. AND BY THE WAY ANY HOUSTON POSTERS HEADING NORTH ARE HEREBY ORDERED TO STOP AND PICK ME UP!!!!
The other side of this coin is that on radar it appears the low has already moved N and W(moving NE)of our area and that would mean we will be in the warmer sector. I f the other low comes in further S though then it could all come to pass as we would have cold air being drawn down by the 1st one with precip being generated by second one. How is that for -removed-?
