Rainfall supply running short - Little rain expected this week

Any chance for rain this week will be limited thanks to high pressure holding firm across the Great Lakes.  While a few showers were seen earlier this morning west of here associated with low pressure, drier air in place will keep the majority of those showers to the west and south.  A dip in the jet stream will take that low through central and southern Illinois later this afternoon and evening and out into Indiana and Ohio by Wednesday.  All we'll likely see is an increase in cloud cover through tonight.  A wind shift to the East Wednesday may keep a few extra clouds around during the day but developing high pressure by the end of the week will help warm temperatures back near 80 degrees across the Midwest.

The next chance for any measurable precipitation will arrive late in the weekend with an approaching cold front.  Again, moisture remains fairly limited with this but enough may get caught up with the low and cold front to produce a couple tenths of an inch.  Time will tell just how much we will receive as the weekend gets closer.  Best timing right now looks like Saturday night into Sunday afternoon.
