PADUCAH – A strong Arctic cold front will arrive this afternoon, bringing a rapid drop in temperatures, from 40 to 20 degrees, likely within an hour. This is accompanied by a strong northwest wind of up to 35-40 km/hour.
Light rain willOnce the front passes, I quickly turn to snow. There may be a heavy snow shower that, in combination with the wind, causes almost white conditions for a short period. The heaviest snow is likely to fall between 3:00 PM and 6:00 PM for most of our area. With the rapid movement of this system, totals will likely be between 1 and 3 inches, although some higher isolated totals of 4 inches or more are possible.
Sudden freezing of moisture on roads could cause extremely slippery and dangerous driving conditions late this afternoon and into this evening, regardless of how much snow falls. Temperatures will likely drop to levels cold enough to freeze, even on prepared roads.
Dangerous wind chills as low as -10 to -20° after 6pm tonight….as low as -20 to -30° by Friday morning. Exposed skin can freeze within 30 minutes.
