Area Forecast Discussion National Weather Service Saint Louis MO 256 PM CDT Fri Jun 14 2024


- Temperatures are expected to remain above normal through next week with high temperatures mainly in the 90s. Sunday and Monday will be the warmest days with peak heat index values in the upper 90s to 105 degree range.

- There is a low chance (20 percent) of showers and thunderstorms over central Missouri late tonight and tomorrow. There are multiple chances (20-30 percent) for scattered showers and thunderstorms across the area next week.

(Through Late Saturday Night)
Issued at 254 PM CDT Fri Jun 14 2024

Latest surface analysis is showing that a surface front extending across far southern Illinois into southern Missouri into southern Kansas. The RAP is showing the front moving back to the north across parts of Kansas and southwest Missouri late tonight in response to a upper trough moving into the Plains. Scattered showers and thunderstorms will develop late tonight when the low level jet interacts with the front. This activity will eventually move into the western CWA tomorrow morning and diminish as the low level jet veers and the instability weakens as it moves to the east.
Saturday night looks dry as the aforementioned upper trough shears out and stays to our north.

Lows tonight will drop down into 60s under a clear sky with light winds with a dewpoints in the 50s. Highs tomorrow will be similar to today with winds turning out of the east under a partly cloudy sky. Winds will turn out of the south on Saturday night keeping lows in the 60s.


(Sunday through Next Friday)
Issued at 254 PM CDT Fri Jun 14 2024

There is reasonable agreement between the global models and the LREF that the upper ridge will move east of the area by Sunday and then expand into a large area of high pressure that will cover the eastern CONUS by the middle of next week. The surface high will move from the Great Lakes to off the northeast coast by early next week. This will allow a warm front to move northeast through the area Saturday night into early Sunday. Thereafter, the low level flow will stay mainly from the south the rest of the period as the front will stay to the north where the westerlies will be shunted north by the upper high. The LREF members are showing some low chance (20-30%) for showers and thunderstorms at times next week as weak systems will move across Missouri and Illinois at the same time a deep flow of moisture will move up from the Gulf of Mexico.

High temperatures will be mainly in the 90s next week as 850mb LREF temperatures are forecast to staying around 20C. The warmest days are still forecast to be Sunday and Monday with highs in the mid- upper 90s and dewpoints in the middle 60s to around 70. This will result in some locations reaching heat index readings of 100-105 degrees during the afternoon hours. After Monday, confidence in reaching heat index levels is not as high as temperature and dewpoints are not forecast to match up to reach critical levels. The NBM IQR is wider Tuesday through next Friday (6-8 degrees) than it is on Saturday through Monday (3-4 degrees) at St. Louis.


(For the 18z TAFs through 18z Saturday Afternoon)
Issued at 1237 PM CDT Fri Jun 14 2024

Dry and VFR conditions are expected through the period. Northerly surface winds will veer out of the east by Saturday morning.
