Forecast Through Friday Night. Update

Over most of the area, temperatures are currently residing in the upper 60's to lower 70's, with the coldest locations over Northwest Indiana.  Dew points are pretty low, mainly in the mid to upper 40's areawide.  Over the next couple of hours, I expect cloud cover to be on the increase, as the first band of precipitation in association with the developing cut-off low advances into the area.  We could have a few showers tonight, but according to radar trends, I expect that most of the rain will remain in central and western Indiana and even then most of the precipitation will have dissipated.  Tonight, lows will only drop into the lower to middle 50's, due to persistent cloud cover moving in from the southwest.  Tomorrow, highs will only reach the lower to middle 60's, depending on the amount of the cloud cover.  I'm expecting overcast conditions to continue through 2 p.m., with thickest cloud cover in the morning hours.  There may be some rain tomorrow especially in Northwest Ohio areas.  My calculated rain chances range from 30% in Northeast Indiana to nearly 70% in eastern parts of Northwest Ohio (Defiance on east).  Rain will generally not be widespread with the rain being more showery in nature, with the greatest chance of precipitation in the early to mid morning hours.  The main band of rain will generally be east of this area.  Friday Night, after a break in rain chances during the afternoon, computer models are forecasting a greater chance of rain by the early evening, with the rain being in the form of showers.  Lows Friday Night will be quite a bit colder than tonight, due to decreasing cloud cover overnight and lower dew points.  Lows will drop to around 44 as the skies clear. 
      Over the weekend, chances of rain will begin to increase each day.  On Saturday, expect mostly cloudy conditions with some scattered showers.  A few heavier showers may pop up to, but that depends on the amount of afternoon heating. On Sunday, rain chances will increase, with showers increasing throughout the day.  Some thunderstorms may also show up to.  By Monday, thunderstorm chances will peak, with widespread rainfall being possible.  Even as rain chances increase, expect temperatures to gradually recover from the mid 60's to the lower 70's by Monday.  Soon this upper level cut-off low will decide to move on with the general flow aloft, bringing back nicer conditions and a faster pattern instead of a more stagnant one.  On a side note, I will have an update to my winter forecast sometime in mid-to late October depending on several things.
