Summer-like conditions continue into last week of October

SHORT TERM:
Near-summer conditions will prevail through this weekend as the region will enjoy highs in the mid to upper 70s under sunny skies.  These temp departures are 15 degrees above normal for the 3rd week in October.  However, record high temps are not expected to be reached.  Unusually warm conditions will continue Monday with highs in the lower 70s.

LONG TERM:
A strong system will impact the area Tuesday into Wednesday.  A strengthening low pressure system will move over the Great Lakes.  Simultaneously, a sharpening upper-level trough will move over the Ohio Valley.  Both systems will bring rainy and windy conditions throughout the day.  1″ to 2″ of rain is expected in areas where the heaviest banding sets up.  Expect periods of rain throughout the day, with some bursts of moderate to heavy rainfall possible.  Conditions will remain breezy, but a few isolated strong gusts may mix down from the low level jet along the edge of the front.  The systems will move out later in the day Wednesday.

Wednesday and Thursday will be cooler, but still normal for this time of year with daytime highs in the low 60s and overnight lows in the mid 40s.  Expect a slight chance of showers Thursday.

By Friday, the trough will have departed and the region will see a return of sunny skies with highs in the low to mid 60s.

MARINE:
River conditions will remain tranquil through Monday.  The approaching systems will bring strong south winds on Tuesday, creating a wind tunnel effect through the valleys and causing extremely rough waves.  Tidal departures will remain normal with a first-quarter moon phase.

HYDROLOGY:
1-2″ of rainfall is expected Tuesday into Wednesday, with periods of moderate to heavy rainfall.  Flooding will not be a concern for main stem rivers or creeks due to the prolonged dry spell, but brief heavy rains could cause ponding on roadways.
