Warm front finally lifts north of the area today. Winds out of the south bring above average temperatures for the first half of this week. Plenty of midday sunshine will help dry things out after that soggy weekend. Highs today will be in the low 80s! For the rest of today, look for breezy conditions & a sun/cloud mix. A few short-lived thunderstorms will develop this afternoon/evening, especially in the mountain counties. Skies will become mostly cloudy in the overnight hours. But most of the lowlands will manage to stay dry through tonight. Look for lows tonight around 60. High water problems still a possibility in some places, especially along the Ohio River.

More unsettled weather is in store Tuesday through Thursday. A series of upper level disturbances ride along a deep upper air trough that cuts as far south as the lower Mississippi Valley. This will usher in more potentially heavy rain and occasional thunderstorms as we trudge through this last week of April.

The timing and track of these disturbances still needs sharpening but will go something like this...Tuesday we'll see a high of 81. We'll see a few peaks of sunshine during the day. Afternoon showers and thunderstorms will develop with that first impulse. This system could produce heavy downpours, bringing about more flooding/flash flooding problems.

The next system will affect mainly the western portions of our state. Again, this system would produce another round of potentially heavy rain & occasional thunderstorms & compound existing high water problems along the Ohio River.

By Wednesday/ Wednesday night, a cold front will bring a juicy dose of heavy rain showers and thunderstorms. That system will track from the Southern Plains, through the Great Lakes, Ohio Valley & Mid-Atlantic states, eventually continuing northeast up the coast. Of course it will be accompanied by the obligatory heavy rain, hail, thunder/lightning, potentially damaging wind and a few tornado outbreaks.

Cooler temperatures behind that front will put daytime highs on Thursday in the lower 60s. We'll also see a few leftover rain showers during the day Thursday & even into early Friday. We'll finish out the work week on the cool side, with temperatures in the upper 50s. Naturally, any additional rainfall could bring flash flooding to the forecast area again.

Warmer air and sunshine Saturday should prevent this week from being a total loss. Then the next system will arrive by Sunday/Monday!

Cooler air by Thursday
