We awakened to a colder morning across the region following the passage of a cold front early Thursday night. Temperatures fell into the 20s with some lows in the teens in far western Kansas. We saw some patchy dense fog and freezing fog in parts of western Kansas as well. Today is literally the "calm before the storm" with cold Canadian high pressure centered over northern Missouri. Although the clockwise flow around this high is bringing our winds around to the southeast and south today, temperatures will wind up colder today than yesterday with highs in the upper 30s and lower 40s across central Kansas, but upper 40s to lower 50s in far western Kansas this afternoon. Morning low cloud cover in northern and western Kansas will break for some sunshine, otherwise skies will be sunny to partly cloudy around the region. Clouds will gradually increase tonight as southerly winds begin pulling moisture northward but tonight remains dry with lows in the teens and 20s. Widespread light precipitation will develop across Kansas on Saturday as moisture continues to increase. Temperatures will still be below freezing at the surface north of highway 50 with freezing rain or freezing drizzle during the day on Saturday. Areas from Pratt to Wichita and farther south see mainly light rain or drizzle as temperatures get a few degrees above freezing during the day. The precipitation becomes steadily more intense during Saturday night with considerable icing of trees, powerlines, roads and sidewalks. The intense storm system now entering the Pacific Northwest will slide east and southeast and become stronger as it tracks near to just south of the Oklahoma state line later Saturday night and Sunday. In the meantime, a bitterly cold Arctic air mass will plunge south through the Plains gradually switching any rain, sleet and freezing rain over to snow in most of Kansas by Sunday morning. Much of central and eastern Kansas could see impactful ice accumulations before the change to all snow Sunday morning. The snowfall can be quite heavy with strong winds out of the north leading to considerable blowing and drifting. Travel conditions will deteriorate this weekend and be very hazardous by later Saturday evening right through Sunday. As a result, a Winter Storm Watch covers much of Central and Eastern Kansas from 9 a.m. Saturday until 6 p.m. Sunday with a Winter Weather Advisory farther west where precipitation is expected to be lighter and less impactful. The bitterly cold Arctic air will set up camp across the region through the middle of next week. KSN Storm Track 3 Forecast from Meteorologist Jack Boston:    Wichita:This Afternoon: Partly cloudy.
