Flash Flood Prediction Program

The Message 2 for Douglas County (NWS Flood/Flash Flood Watch) has been allowed to expire at 6:00 PM and the additional Message 1’s for the remainder of the District have also been allowed to expire at 6:00 PM.

Behind the upper level disturbance that moved through during the early afternoon drier air from the west is moving into the District currently pushing the moist air further east onto the plains and this drier air mass will completely remove the threat for heavy rainfall for the rest of the day and provide drier conditions over the coming days! There could be a an isolated rain showers or weak thunderstorm into the evening but there is no longer a threat for heavy rainfall and most areas will be dry from this point forward.

Sunday (Father’s Day) is expected to be a generally dry day over the District with temperatures warming into the middle 80’s which is warmer than we have experienced this year and temperatures may reach or exceed 90 degrees on Monday and Tuesday with dry conditions expected to continue. Summer is FINALLY arriving with a more “normal” weather pattern for this time of year expected to unfold over the coming weeks.

STORM RAINFALL POTENTIAL AND DURATION: Isolated rain showers and possibly a very isolated weak thunderstorm produce a trace to 0.2" of rain. Most areas will be dry.
