We've had A LOT of snow in southern Wisconsin this week but clouds are making it hard to discern the extent of the fresh snow cover. Fortunately the Day Cloud Phase distinction RGB solves this problem with snow shaded green, revealing the general storm track. #IAwx #ILwx #WIwx

RT @NWS: Several clusters of severe storms are expected from central Texas across the ArkLaTex and into the lower Ohio Valley through tonight. The greatest threat for tornadoes, large hail and damaging winds will be from the ArkLaTex across western Arkansas into southeast Missouri, including potential for strong to potentially intense tornadoes.

Review your severe weather safety procedures for the possibility of dangerous weather today. Stay tuned to NOAA Weather Radio, https://t.co/qk3BcVP5M8, or other media for watches and warnings.
