AREA FORECAST DISCUSSION National Weather Service Wilmington OH 1029 PM EDT Mon Sep 27 2021

SYNOPSIS. A weak cold front across the Great Lakes will drop south overnight and slide through the region on Tuesday. High pressure will build in behind the front and persist through the remainder of the week.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. A disturbance moving through overnight will lead to some shower activity. Cannot rule out a few rumbles of thunder, however kept out of the forecast at this time. Decreased temperatures slightly across far northwestern portions of the region where the frontal boundary will be. Although wind gusts have generally subsided across the region, a few isolated wind gusts will still be possible.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. East-west oriented cold front will stretch across northern Indiana and Ohio at the beginning of the period. This will push through the forecast area during the day, perhaps not clearing northern Kentucky counties until the evening. Moisture will be quite limited, so this will come through primarily dry. There will be an increase in clouds near and after the boundary. Southern areas will see highs near persistence since the front is coming through later in the day. Northern counties will be a little cooler than today but still above normal.

High pressure will start to build in Tuesday night. Lows will be closer to normal across the north but stay in the upper 50s near and south of the Ohio River.

LONG TERM /WEDNESDAY THROUGH MONDAY/. To start the period, high pressure builds over the Mississippi Valley while a closed mid-level low over New England slowly moves east. The low to the northeast brings dry northerly flow to the region. Combined with ridging from the west, warm dry weather is expected through the end of the week. High temperatures gradually cool from around 80 to the mid 70s with a warmer trend in the southwest.

There is still quite a bit of uncertainty in the expected weather pattern next weekend. Differences still arise in the synoptic flow pattern between global models and ensembles. The GFS is still more aggressive in dampening the H5 ridge, leading to a faster onset of a shortwave trough that will usher in precipitation across the CWA. However, the 12z run has slowed down the timing of the shortwave compared to previous runs, but still begins to push rain showers into our fa by midday Saturday. Meanwhile, the ECMWF holds onto the H5 ridge a bit longer as it becomes more positively tilted through the Midwest. With the ECMWF holding onto the ridge for a longer period, this model actually keeps the forecast dry through the weekend before a shortwave trough finally begins to propagate through late Sunday night - the timeframe when precipitation is brought in. Started to hedge more towards the Euro solution, with better chances for rain expected late Sunday into Monday. Temperatures will be closer to seasonal normals over the weekend and into the beginning of the next work week.

AVIATION /02Z TUESDAY THROUGH SATURDAY/. VFR conditions will start out the TAF period. A frontal boundary will work into the region tonight into Tuesday. The best chance for some precipitation will be around KCMH and KLCK and have a VCSH mention in those locations overnight. There will also be the potential for some LLWS around KDAY and KILN for a few hours. Heading into Tuesday morning and into the afternoon hours, start to see the wind shift with the frontal boundary. There are some indications that there will be the potential for some MVFR cigs to develop near and after the frontal boundary. There is a better chance for this across the northern TAF sites.

OUTLOOK . No significant weather expected.
