Updated for 12Z TAF issuance.
Key messages
1) Quiet weather and above-average temperatures continue. Light rain expected late Sunday into Monday.
2) Additional rain chances next week
Discussion
KEY MESSAGE 1: The potential for hazardous weather remains low throughout the week and into the weekend as high pressure persists. Temperatures are expected to trend around 10 degrees above average, through the probability of record-high temperatures remains low.
Precipitation chances increase late Sunday into Monday as a weak disturbance develops near the Great Plains and tracks eastward. Forecast rainfall amounts have trended downward over the past 24 hours, with less than a 30% chance of exceeding 0.50 inches.
KEY MESSAGE 2:
Over the past 24 hours, long-range models have increasingly indicated the development of a large-scale low-pressure system over the central CONUS late Monday into Tuesday. Depending on the evolution and track of this system, period of heavy rainfall could impact portions of the Ohio River Valley by midweek. Current probabilities indicate a 20-30% chance of rainfall exceeding 1 inch.
Aviation
BKN to OVC high-level clouds are expected to scatter by this afternoon. VFR conditions and light winds are expected over the next 24 to 48 hours.
On Friday, a passing cold front over the Great Lakes may return cig restrictions mainly to the northern ports.
Outlook: Light rain is expected to return late Sunday into Monday with large-scale disturbance.
