High pressure will continue to provide fair weather today.
Temperatures early this morning will be in the mid to upper 40s.
Highs today will be near 70 degrees. A weak upper level
disturbance lifting through the Ohio Valley will bring an increase
in cloud cover to the region. There is a low chance for light
rain along and southeast of the Route 24 corridor during this
time. High pressure then will build back into the region over the
weekend into early next week, resulting in dry conditions and
warming temperatures.

An upper level wave will move out of the plains, digging into the
Ohio Valley over the next 24 to 36 hours. High pressure should
remain in control of most of the area even as it shifts slightly
to the east and elongates from west to east. The upper level wave
will cause low pressure to develop over southern Ohio Friday night
with an area of rain extending northwest from the low. models
still bring some of this rain into far se sections of the forecast
area friday night so will maintain slight chance to chance pops.
no impact in temperatures is expected with this wave as any colder
air remains trapped north of the region. lows will be in the 40s
both tonight and friday night with highs friday edging towards 70.

Issued at 300 PM EDT Thu May 19 2016

2 each day. Low level moisture will slowly increase towards the

waves will attempt to impact the region and attempt to end the
mainly dry period. Will maintain superblend of pops in later
periods in the slight chance to chance range.
