Temperatures are beginning to become more fall like after a strong cold front and canadian air mass moved through Kentucky over the weekend. Surface high pressure has built in behind with winds remaining out of the north allowing the colder temperatures to continue to be advected into Kentucky.
Another area of low pressure has begun to develop over the Canadian border. A trough continues to deepen to the west over the Canadian border and propagate to the east into the week brining more cold temperatures and chance of showers by Tuesday night as another cold front develops and moves east over Kentucky. As with the last Canadian air mass, this one will also be dry which will inhibit precipitation chances. Both NAM and GFS models paint a line of precipitation moving through Wednesday ahead of the front. With a tight band of moisture out ahead of the front, this looks bleak. A few stray showers/sprinkles cannot be ruled out Tuesday night into Wednesday. Frost advisories are likely to remain into the week as cold overnight lows and dew points in the 30’s combine.
Monday 10/8: High, 62. Low, 39 . 10% chance of precipitation, morning frost likely. Winds chilly out of the north.
Tuesday 10/9: High, 68. Low, 43. 20% chance of precipitation, morning frost likely. Front approaching overnight Tuesday with colder temperatures filtering in behind. Winds will remain northerly.
Wednesday 10/10: High, 63. Low, 39 . Front passes through with colder temperatures in behind. Morning frost likely. Temperatures drop further with passage of front. Winds chilly and out of the north.
