Key Messages
- Conditions remain calm and clear leading into the weekend.
- Hurricane Isaias will make landfall this evening and is expected to bring cloud cover into the forecast area on Saturday.
Friday Night – Saturday
Current conditions are in the upper 80s this afternoon with a clear sky that stays clear through the remainder of the night, due to a high-pressure system over southern Missouri. The main weather story shifts the attention toward Hurricane Isaias as it seeks to make landfall off the coast of Florida this evening. Conditions remain calm and dry through the weekend, with Isaias bringing increased cloud cover over the forecast area on Saturday. Rainfall is not expected in Columbia this weekend, as Hurricane Isaias’s path is projected to impact mostly the southeastern United States. Cloud cover is expected to remain mostly in the upper levels, with 700-mb and 850-mb relative humidity values below 50-60%. Daytime temperatures for Saturday will continue to be unseasonably warm, with highs in the middle 80s which is around +20°F warmer than average for this time of year (68°F).
Saturday Night – Sunday Night
Clouds will begin to decrease Saturday night, with mostly sunny conditions expected on Sunday. A ridge of high pressure is expected to build into the Great Plains on Sunday, slightly boosting temperatures higher than the previous day into the upper 80s. This ridge will continue to amplify as the week begins, with quasi-zonal upper-level winds. These indices will lead to quiet and calmer conditions for Sunday into Monday. Overnight Sunday, the low-level jet will begin to creep in over Missouri, with winds from the southwest. These winds will begin to mix down toward the surface and shift winds to the southwest, indicating WAA into mid-Missouri. The aforementioned indices of the amplifying ridge and southerly winds through the boundary layer will create near record-breaking temperatures into Monday.

Key Messages:
- WWA following a warm front draped over northern Missouri will induce unseasonably warm temperatures (90°F ) for Friday.
- Moisture transport following Hurricane Isaias will cause increased cloud cover for Saturday. No rainfall is expected for Columbia, Missouri.
Currently, there is split flow at 250mb to the North and South of the CWA, with a lack of divergence of the area hinting at calmer conditions throughout Friday. RH values at 700mb and 850mb stay below 70%, influencing a lack of cloud cover. A surface-level low-pressure system currently resides over eastern Nebraska, with a warm front draping over northern Missouri. WWA behind the warm front, along with a lack of cloud cover increasing diurnal heating, will raise the high temperature to 90°F for Friday.
Saturday’s main focus will be the impacts of hurricane Isaias. Conditions are reliant upon the track of Isaias, as currently it’s projected to stay eastward of Missouri as it moves from the Gulf. The hurricane will advect upper-level moisture (>70%) increasing cloud cover beginning Saturday 21z. Columbia is expecting no rainfall, with the track having the greatest impact on the southeastern CONUS. Beginning Sunday 15z, moisture will begin to move out of the area allowing cloud cover to decrease overnight. Temperatures will begin to decrease with the Saturday night low dropping down to 57°F.
Future forecasters should monitor the track of Hurricane Isaias to determine any changes in rainfall amounts for Columbia.
