What Has Changed

Overall forecast and message remains unchanged.

Key Messages

1) Above normal temperature with dry weather highly likely until at least late next week.

Discussion

KEY MESSAGE 1... Ensemble guidance remains in strong agreement that persistent upper ridging and surface high pressure will dominate the region through most of next week (if not longer). This will guarantee dry, sunny, and warm conditions. Precipitation chances remain below 10% through Thursday morning before cloud cover gradually increases ahead of an approaching trough.

Uncertainty in ridge placement and trough movement grows by late next week with increasing rain chances into the weekend. However, 24-hour probabilities generally never exceed 50% during this timeframe, suggesting rain likely confined to one period (rather than multiple rounds) with models uncertain which of Friday/Saturday/Sunday sees the best chance.

Aviation

High confidence VFR continues through much of next week. Light E/SE winds are expected through Sunday. River valley fog may impact isolated sites (FKL/HLG) with IFR to LIFR visibility through 13Z this morning before diurnal mixing after sunrise.

Outlook... Outside of any morning river valley fog, VFR is highly likely through Thursday under high pressure.
