Weather train keeps rolling

Day 1-3 rainfall.jpg

Next weather system ready to deliver another half inch of rain to southeast Minnesota.

Our weather is like a broken record this month. It keeps skipping ahead to the same spot on the weather map.

After a brief break today, an active jet stream overhead is ready to deliver another low pressure wave for Friday. It looks like rain will stay south of a Sioux City to Mason City line today. Then as the next wave approaches, the rain will move north tonight. Rain should reach the Twin Cities area after midnight, and be here in time for another rain slicked rush hour Friday morning. Another half inch of rain could fall in the metro and southeast Minnesota Friday.

Surface weather map shows the next low pressure wave near Kansas City ready to push rain north tonight.

When weather systems speed up in the fall, the weather map tends to repeat every 48 hours in the Midwest. Thus our Wednesday-Friday-Sunday rain systems are right on schedule. With faster moving weather systems, the forecast models have more room for error. That keeps forecasters on our toes this time of year, and forecast changes can come quickly. I’m keeping a close eye on a weather system that could bring signifcant rain or snow to the area next Wednesday.

Wednesday’s system brought snow to northern Minnesota. It looks like Friday’s system will be just warm enough to prevent any significant snowfall accumulations.

With 4.35″ of precip in the Twin Cities rain gauge this month we’re running over 200% of average precipitation this month. We’ll make a run at a top 10 wettest October slot Friday as we move closer to the 4.94″ threshold for that record.

Enjoy a drier day today. It appears our low stratus season is here early this year. The clouds should hang in most of today, but there may be a few sunny breaks, especially north of the metro.
