SATURDAY'S BLOB OF RAIN

This is the radar image as of 12:35 pm on Saturday. A blob of rain with isolated storms is tracking northwestward at 30 mph. The heaviest rain is concentrated southeast of I-44. A flash flood warning is in effect until 5pm across southern Ozark, northern Marion and northern Baxter county. Radar estimates are greater than 2" across MO/AR border, which has fallen since 8 am. Be careful when driving today across the warned area because runoff from the heavy rainfall will cause flooding of small streams, creeks, county roads as well as farmland.

STRONG FRONT ARRIVES ON MONDAY-TUESDAY

A strong cold front approaches the Ozarks on Monday. The image above is the frontal position forecast for Monday morning.
There is a slight risk for severe storms on Monday afternoon and evening across western Missouri. The main risks are damaging winds and hail.
The front is expected to produce heavy rainfall which could lead to flash flooding. The image above shows the amount of rain forecast to fall from now until Tuesday morning. Heavy rain along the front will start impacting our western counties on Monday afternoon and evening and then slowly spread eastward with time. H.P.C. is forecasting 1-2" of rain with locally higher amounts.
