A Quiet End of the Week Forecast

Days at a Glance:
Thursday: High, 75. Low, 60.  Frontal boundary moving through with wind shift from southerly winds into northwesterly winds at 5-10 knots. A few pre-frontal showers possible with a slight cool down behind the front. Clearing skies and sunshine.

Friday: High, 70. Low, 50. Clearing skies with sunshine. Winds from the north becoming more northeasterly at 7-12 knots.

Saturday: High, 75. Low, 52. Clear in the morning with clouds increasing into the afternoon/evening. Winds becoming more easterly 5-10 knots.

Sunday: High, 77. Low, 58. Clouds persisting through most of the day with few breaks of sunshine. Winds out of the east from 5-10 knots. Chance of isolated showers 20%.

Discussion:
Frontal boundary moves in Thursday with a cool down in temperatures. It is possible we will still see a few scattered pre-frontal showers develop with highs in the mid-70's and lows in the 60's. Any areas that receive a passing shower may see slightly lower temperatures than predicted lows. Friday will bring clearing skies and sunshine with highs in the 70's and lows in the 50's. Saturday will bring sunshine a warm up back into the mid-70's with lows in the 50's as a ridge of high pressure brings subsidence over the area. The next chance for showers will come Sunday as the ridge begins to break down and weak upper level disturbances make their way across central Kentucky.
