Is this legit?

Everywhere else says Rain/Snow and at least 40 degrees high for Monday...

:rolleyes:

When will you people quit using weather .com....the absolute worst place to get long range forecasts...

Area forecast discussion

National Weather Service Greenville-Spartanburg SC

641 PM EST Thursday Jan 6 2011

Long term /Sunday night through Thursday/...

as of 300 PM Thursday...confidence continues to increase regarding the

potential for an early week winter storm across the County warning forecast area. Now all

12z Ops runs of the European model (ecmwf)/GFS and Gem show a Miller a type system

moving south of the area Monday and Tuesday. The low takes a slow track

from the la coast sun evening...reaching Cape Hatteras by late Tuesday.

Deep moisture and synoptic scale lift move into the area Sun night

and continues on Monday. This lift moves east Monday night. However...

deep moisture and low level isentropic lift remain across the area

Monday night and finally moves NE of the area Tuesday. Forecast soundings show a

prolonged period of a near zero isothermal layer across much of the

area. The 850 mb zero line does move north into the County warning forecast area. However...

this could be overdone if dynamic cooling affects take over. This is

beginning to look like the January 1988 snow storm where a weak low

pressure moved through the Gulf and a prolonged period of isentropic

lift remained over the area...even though synoptic lift was weak. This

produced a large area of 1 foot accums. It is too early to say

whether this much snow develops...however it is in the realm of

possibility.

I have likely pop moving in Sun night and continuing through Monday.

This results in snow across all the County warning forecast area Sun night...with sleet

mixing in south of I-85 during the day Monday. This p-type pattern

continues Monday night and Tuesday as precipitation ends from the SW. Then a

prolonged period of northwest flow snow develops across the Tennessee border

counties Tuesday night through Thursday. Even with a conservative approach to

temperatures and quantitative precipitation forecast...which I have taken...snowfall well above warning

criteria is possible across all the County warning forecast area Sun night through Tuesday...before

additional snowfall develops across the Tennessee border counties through Thursday.
