COOL, CLOUDY WITH A FEW LINGERING SHOWERS THROUGH MIDDAY
The light rain across the metro area continues this morning from last night/yesterday’s storms will fully dissipate by midday today. Afternoon highs will be limited due to the rainfall from last night and this morning, only reaching the upper 60s. Rainfall today will be minimal with generally between a trace and 0.20”. Cloud cover will be overcast in the morning, then will be partly cloudy later, as well as calm winds throughout the day and into the night. Overnight will be mild and dry with lows dropping into the 40s on the plains with upper 30s possible along the higher terrain foothills.
STORM RAINFALL POTENTIAL AND DURATION: Typical showers will produce a trace-0.20” total in 10-30 minutes.

WORST CASE SCENARIO: A moderate shower or weak thunderstorm will produce rainfall of 0.20 to 0.40” total in 10-30 minutes.

A LOOK AHEAD: Warmer Saturday as high temperatures reach the mid to upper 70s under mostly sunny skies. High-pressure starts to build on Sunday bringing high temperatures back to a more seasonable low 80s with continued sunny skies throughout the day. Similar conditions remain in place on Monday with highs remaining in the low 80s.
