... High pressure will maintain generally dry weather through the weekend. Rain chances return Sunday night and Monday with a crossing cold front.
NEAR TERM /THROUGH TONIGHT/... An amplifying upper ridge will maintain high pressure in the Ohio Valley tonight. Amid light wind, clear sky and low moisture, overnight minima will drop again generally into the upper 40s-mid 50s. Sheltered areas in the ridges could fall lower in the 40s. These conditions may support patchy fog, especially in the river valleys as the cool air interacts with the warmer water.
SHORT TERM /FRIDAY THROUGH SATURDAY/... Mid- and upper-level ridging is expected to amplify across the Upper OH Valley through Sat as a sfc high drifts swd. Increasing H5 height and developing swly flow aloft should sustain the ongoing warming trend.
Some models indicate showers developing Saturday with a brief flattening of the upper ridge, but these seem to be driven by moisture advection known to trip up model parameterization for precipitation. Forecast soundings suggest a strong plume of warm air at H85, which likely will limit the depth of any convection despite increasing low-level moisture. Chances for showers are minimal, but non-zero, with greatest potential on Sat from ZZV-UCP.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... The upper ridge will shift ewd thru the weekend ahead of a strong trough in central Canada, but the timing and strength of the trough remain uncertain. A slowing trend has been apparent in its arrival over the last several model runs owing to potential for the trough to close off, thus delaying arrival of its attendant cold front and onset of precipitation.
Given this uncertainty, it is unclear precisely when the greatest chance for rain will come, but it is likely to be somewhere in the Sun night-Mon timeframe.
Thereafter, dry, cooler conditions are expected in the early half of next week.
