What forecasters said that day
The local office's own words before this winter storm watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Memphis, TN wrote its last area forecast discussion before this winter storm watch went out at Feb 12, 11:24 AM CST, 3 hours 53 minutes earlier.
Area forecast discussion, Feb 12, 11:24 AM CST, 3 hours 53 minutes before
Area Forecast Discussion National Weather Service Memphis TN 1124 AM CST Fri Feb 12 2021 .UPDATE... Updated for the 18Z Aviation Discussion && .PREV DISCUSSION... /issued 948 AM CST Fri Feb 12 2021/ UPDATE... Arctic air continues to plunge into the Mid-South this morning. Current temperatures range from the mid 20s near the AR/MO and KY/TN borders to the mid 30s across Monroe County, Mississippi. Temperatures won't warm too much as cold air advection is occurring across the region. A few showers continue to skirt portions of Northeast Mississippi at this time. Will update to add some small POPS. Otherwise, rest of the forecast looks good. KRM DISCUSSION... /issued 524 AM CST Fri Feb 12 2021/ Surface analysis this morning places a quasi- stationary boundary located over Northern Georgia and South Carolina and a cold front from Southern Alabama back into the Northern Gulf of Mexico. Meanwhile, across the Mid-South, LAPS soundings and WSR-88D Vad Wind Profile depicted a steep low level arctic inversion. This steep inversion combined with NNE boundary layer winds and some upper level forcing associated with a departing upper level jet produced some light freezing drizzle Thursday evening into early this morning. KNQA/KGWX WSR-88D radar trends depict light precipitation occurring over Northwest Mississippi moving ENE. As of 4 AM CST, temperatures across the Mid-South are predominantly in the 20s with lower 30s occurring over NE Mississippi from Tupelo to the southeast. Wintry precipitation concerns will remain the primary focus in the forecast for the next 7 days in this morning/s forecast issuance. Radar trends over the past hour have indicated the development of light precipitation over areas just southwest of Oxford and possibly freezing rain as indicated by LAPS soundings. A Winter Weather Advisory was issued early this morning through 6 AM for the freezing drizzle and may need to be extended for a portion of North Mississippi to account for the freezing rain. Otherwise, mainly precipitation free weather is expected across the Mid-South today with temperatures remaining mostly below freezing. A subtle and weak shortwave trough will move across the Lower Mississippi Valley tonight. There is a potential for some light rain/freezing rain over Northeast Mississippi with precipitation amounts remaining relatively light around a couple of hundredths at best. This will continue to be assessed throughout the day in the event headlines are needed for later tonight across the aforementioned area. Gusty NNE winds combined with lows Saturday night in the teens may result in wind chill values dropping into the single digits below zero across portions of the Missouri Bootheel and Northeast Arkansas. This may necessitate a Wind Chill Advisory if trends continue in subsequent forecasts. Models are continuing to show an potent open wave trough dropping out of the Rockies and into the Southern Plains on Sunday then rotating through the Middle and Lower Mississippi Valleys Sunday night into Monday night. It appears that a lead shortwave trough may enter the the region Sunday afternoon into Sunday evening, resulting the development of precipitation across the area with the best chances of precipitation occurring on Monday as the upper level trough rotates through the region. Mixed precipitation types will remain a challenge with this system with freezing rain, sleet, and snow all possible especially along and south of I-40, and mostly sleet and/or snow to the northwest. It appears that headlines may be warranted for this next system but exact precipitation types along with amounts will continue to be further assessed in upcoming forecasts. Long term models indicate yet another upper level trough will move through the Lower Mississippi Valley for mid to late next week bringing another chance of wintry mixed precipitation to the Mid- South. CJC && .AVIATION... 18Z TAF cycle Current VFR ceilings across northern sections of the Mid-South will end by this evening as low clouds currently over the remainder of the region move back north. Most areas will see IFR ceilings for this afternoon through Saturday morning with some improvement to MVFR ceilings by the end of the forecast period. Winds will be from the north at around 10 knots for much of the forecast period. ARS && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. &&
