Cool, rain and high water for Memorial Day Weekend

The timing is poor for those wanting to get out for the first “unofficial” day of some, the Memorial Day Weekend. Rain and cool weather will be in the way for everyone. Flooding concerns have closed many popular camping areas as well.

Here is what we are looking at for the weekend:

Two more systems are still forecast to impact the area bringing widespread precipitation Friday/Saturday and then Sunday/Monday. Snow levels continue to stay lower than they were earlier this week and could alleviate some flooding potential by limiting the amount of rain falling on the ripe snowpack.

* Heaviest precipitation period is expected with the Sunday/Monday system.

* Worse case scenario: Precipitation totals in excess of 1 inch of liquid on the high plains with up to 2.5 inches in the mountains along the Rocky Mountain Front. Central Montana mountains could see up to 2 inches.

* Most likely scenario: Precipitation totals 0.50 to 1 inch of liquid on the high plains with 1 to 2 inches along the Rocky Mountain Front and 1 to 1.5 inches over the Central Montana mountains.

* Some precipitation is expected to fall as snow over the mountains above about 5500 feet and will not cause as much runoff as an all rain scenario.

* Reservoirs are filling up and most reservoirs along the Rocky Mountain Front are full or will be filled by late this weekend based on current inflow rates.

The latest pre-Memorial Day weekend storm system is continuing to push across the state with the Central and Eastern areas seeing the best bet for rain with some thunderstorms also possible this afternoon and tonight. Early this morning Great Falls saw about .15″ of rain at the airport.

Flooding concerns continue over a large area of the state through the Holiday weekend, rising water, plenty of rain and cool temperatures.

Overnight mostly cloudy with a low near 40 and gusty winds with a 40% chance of rain showers.

Friday cloudy and breezy with a 50% chance of rain showers. Wind gusts near 30 mph from the southwest.

Saturday cloudy with an 80% chance or rain and thunderstorms. The high only 50 degrees and still breezy.

Sunday partly sunny with a 50/50 chance of showers and warmer with a high in the upper 50’s.

Memorial Day mostly cloudy with rain likely and a high in the upper 50’s.

By Tuesday we dry out, the sun returns and the temperature climbs to the mid and upper 60’s.

Be sure and check the road report on our website frequently and please be very careful around water this weekend. Normally small streams have turned into rivers, closing many campgrounds for the weekend as well.

Have a good evening!
