Both Lubbock and Midland in Texas had record breaking low maximum temperatures of 14 yesterday. El Paso, TX had a high temperature of 15 yesterday, breaking the all-time record low maximum of 17 set on January 10th, 1962. The temperature at El Paso is 2 as of 7AM MST. The old record for the month of February was 8. Flagstaff, AZ had a high of 12 yesterday, which is the 7th lowest all-time on record. Yesterday morning the low at Flagstaff was -1, the wind chill was -23, winds gusted to 41 mph, and dewpoints both today and yesterday have been as low as -21. The temperature at Grand Canyon at 7AM MST was -1. The high at Tucson yesterday was 42, breaking the record of 43 set in 1956.

Winter storm warnings (pink) have been issued from southern Mississippi to southern Texas including Brownsville:
Forecast soundings indicate that significant sleet and freezing rain accumulations are possible in these areas.
A band of heavy rain developed in Illinois ahead of the main system:
On Thursday, February 24th, this storm produced a significant severe weather outbreak across the Lower Mississippi and Tennessee Valleys:
On the north side, winter storm warnings were issued from Kansas to Maine.
The main convective hazard was from damaging wind, but some tornadoes formed on the leading edge of the squall line.
Bow echo moving through the Memphis area:
Squall line at 9:48 CST:
Bow echo hitting the Nashville area, where two EF2 tornadoes were confirmed:
0Z RUC analysis had wind speeds as high as 60 knots at 925 mb, 68 knots at 850 mb, and 87 knots at 700 mb:
With winds veering about 45 degrees from 925 mb to 700 mb, helicity values were off the charts:
A RUC sounding for Memphis shows how much wind speeds increased just above the surface.
By 3Z, the 850 mb low level jet strengthened to over 80 knots, producing even higher helicity values:
The cold which hit the Southwest early this month penetrated well into Mexico causing a huge loss of crops.
