Nice Sunday….conditions expected to change.

Conditions for your Sunday are expected to clear out nicely as cold but sunny skies prevail.  Morning temperatures have reminded many that winter is hanging tough with lows dropping into the upper 20’s across south-central Kentucky.   A weak shortwave is currently passing overhead as the responsible trough will act to clear out the remaining flurries and embedded snow showers across the region.  A decrease in intensity/coverage is expected with the progression towards our east through the late-afternoon hours.  Skies should continue to clear from west to east as temperatures struggle to reach the mid 30’s for today.

Monday, we’ll begin to turn our attention towards a surface low that will begin to organize during the morning hours as an upper trough digs southeast into the Great Plains.  Isentropic lift associated with the northward advancement of the warm front will help generate bands of light precipitation across the Mississippi Valley tonight, before moving eastward into our area by tomorrow morning.  A light mix is expected although chances for precipitation will be very light as temperatures will warm up quickly over south-central Kentucky.  Highs are expected to reach the low 50’s over our area with temperatures in the upper 40’s towards our north and east.  Conditions will begin to change as we head into the evening and overnight hours.  An elongated trough with an axis extending from parts of North Dakota through central Missouri with an increased southerly flow ahead of this system will help increase moisture values through the overnight hours. This moisture, accompanied by a region of strong isentropic lift passing through will allow a good shot for precipitation as our area could see moderate to heavy rainfall.  Low temperatures across the area are expected to drop into the upper 30’s, low 40’s under mostly cloudy skies.
