Clouds will continue to thicken this afternoon as temperatures hover in the upper 30s. Light snow will develop late this evening, and spread east into the overnight hours as a weakening low pressure system crosses the Ohio Valley. Most of this storm system will cross the Bluegrass Region in the form of snow, with a mix of snow, sleet and eventually rain in southern Kentucky. Tuesday's morning commute may be slick and dangerous, as wintry precipitation continues to fall across at least the northern half to two-thirds of the area. On Valentine's Day, rain will slide farther north as temperatures climb to near 40 in Lexington, but leftover precipitation will be light. Total snowfall will generally be an inch or less, with the best chance for a full inch of snow being in the far northern and western part of the Bluegrass Region. Spotty flurries and sprinkles may linger into Tuesday evening or Tuesday night. A new disturbance will produce more precipitation on Wednesday evening and Thursday. A brief mix on Wednesday evening will quickly change to milder rain on Thursday as highs climb into the lower 50s. Friday will be seasonable and dry with high pressure passing nearby. A southern storm system will pass to our south on Saturday, although there is still potential for a light wintry mix in southern Kentucky, depending on the track that storm takes. A flurry or two will be possible on Sunday.
