30.2 by my Wx Bug (live station near me).

JenyEliza · #122 Postby **JenyEliza** » Wed Dec 14, 2005 10:17 pm

30.0 now.

JenyEliza · #123 Postby **JenyEliza** » Wed Dec 14, 2005 10:21 pm

29.6....I'm not believing this.

I just changed my Wx Bug station to check...and by McCollum it's around 33. Changed it back to the one near me, and it's 29.6, so don't know what to think.

:think:

You need to go see if it's malfunctioning because I don't buy it either. :lol:

DP is up to 27 at Atlanta at 10pm...

From 33.6 @ 10 PM to 32.4 now. Jen, how far from McCollum are you? I'm about 4 or 5 miles east of there.

With biggest precip now moving in, everybody is wet bulbing due to evaporative cooling effects. Temperatures dropping and dewpoints rising. Still should get to freezing, and probably just a bit below at Atlanta as wet bulbing continues. Its already 33 there (official)

Hmmm, don't know in miles. About 25-30 minutes driving, no traffic via E-W Conn/Barrett Pkwy/41.

Its a Wx Bug station (live) at a middle school not too far from me...I can't check it.

31.8 now and elevated surfaces of my deck are beginning to ice over.

JenyEliza · #131 Postby **JenyEliza** » Wed Dec 14, 2005 11:09 pm

Updated graphic of current conditions. We are just inside the blue shaded area.

Going out to check conditions right now. Back shortly to update.

JenyEliza · #133 Postby **JenyEliza** » Wed Dec 14, 2005 11:15 pm

Dogwood trees already iced over. Ice very thin...probably 1/10th or less. Car is not frozen--yet. Driveway not slick....

Very cold. :jacket:

MESOSCALE DISCUSSION 2564
NWS STORM PREDICTION CENTER NORMAN OK
0944 PM CST WED DEC 14 2005

AREAS AFFECTED...NRN GA / NWRN SC / WRN NC / WRN VA

CONCERNING...FREEZING RAIN

VALID 150344Z - 150945Z

FREEZING RAIN WITH HOURLY RATES APPROACHING 0.10 TO 0.15 INCH IS
EXPECTED TO DEVELOP ACROSS NRN GA/NWRN SC AND SPREAD NEWD ACROSS WRN
PORTIONS OF NC AND VA BY 15/12Z.

00Z UPPER-AIR OBSERVATIONS INDICATE THAT FORCING ASSOCIATED WITH A
COUPLED UPPER JET STRUCTURE AND LOW-LEVEL WAA ARE THE PRIMARY
PROCESSES DRIVING LARGE PRECIPITATION SHIELD CURRENTLY OVER THE
LOWER MS VALLEY INTO THE CNTRL GULF STATES AND TN VALLEY. ERN EDGE
OF THIS PRECIPITATION SHIELD IS RAPIDLY EXPANDING NEWD ACROSS NRN GA
WHERE SURFACE WET BULB TEMPERATURES ARE SUB-FREEZING. 00Z FFC
SOUNDING SHOWS THAT LITTLE SATURATION IS NEEDED AROUND 850 MB TO
SATURATE VERTICAL PROFILE AND GIVEN CURRENT OBSERVATIONS THIS HAS
ALREADY OCCURRED.

DEEP-LAYER FORCING FOR ASCENT...PRIMARILY FROM THE TWO
AFOREMENTIONED PROCESSES...IS FORECAST TO DEVELOP ENEWD
OVERNIGHT...SUSTAINING ONGOING PRECIPITATION SHIELD ACROSS THE
CNTRL/SRN APPALACHIANS AND ADJACENT PIEDMONT REGION. STRONG
LOW-LEVEL WAA ATOP SURFACE WEDGE FRONTAL ZONE IN IMMEDIATE LEE OF
THE APPALACHIANS WILL RESULT IN A QUITE FAVORABLE VERTICAL THERMAL
STRATIFICATION FOR FREEZING RAIN WITH A 3-4 C WARM NOSE DEVELOPING
AROUND 850 MB.

Hey Jen you might want to change the thread title. Lots of people gonna see more than cold rain.

Website · #137 Postby **Brent** » Wed Dec 14, 2005 11:32 pm

I think it's time for FFC to wake up... no update in almost 5 hours???

joe_koehle · #138 Postby **joe_koehle** » Wed Dec 14, 2005 11:50 pm

not icing yet in carollton, ga, but i think we probably won't escape some accumulation--it's getting frickin cold out and it's pouring

ga_ben · #139 Postby **ga_ben** » Wed Dec 14, 2005 11:55 pm

I'm at 31.5 and even my deck floor is icing over.

Yeah...but the rest of the winter will probably be cold rain...and we'll be able to use it then.
