- | Continued NW upper-level flow will result in slightly cooler high temperatures today which will reach the upper 70's to around 80 across the District. Mostly sunny skies this morning with clouds increasing this afternoon bringing a chance for rain showers/isolated thunderstorms this afternoon and evening favoring portions of the southern District. |
- | Thunderstorms will first become possible over the foothills and Palmer Divide between 1-3pm. After 3pm thunderstorms will become more likely over the plains with best chances for thunderstorm activity through about 9 or 10pm this evening. With a slight chance for lingering rain showers until 1-3am Tuesday morning before skies begin to clear out. |
- | Surface moisture will be modest through the early afternoon with dew points in the mid 40's. However, models indicate decent upper-level support today along the Palmer Divide which could provide enhanced lift along southern portions of the District and has the potential to initiate stronger storms with moderate to heavy rain. Storm motions will be relatively fast from W/NW to E/SE between 10-15mph, which will help limit point rainfall amounts. Although a slower moving storm that formed along an outflow boundary has increased potential for heavy rainfall. |
WORST CASE SCENARIO: A large strong thunderstorm or a slower moving/stationary thunderstorm will have the potential to produce 0.5-0.8" in 10-30 minutes and up to 1.5" in 60 minutes or less.
A LOOK AHEAD: High temperatures remain cool Tuesday in the low 80's across the plains with mid to upper 70's along the foothills. A chance for rain showers/isolated thunderstorms will be possible each day this week, with chances increases Thursday and Friday. Temperatures will begin to be more seasonal after tomorrow, back into the low 90's for both Wednesday and Thursday.
