Good Sunday bloggers,

We are tracking three weather features, two storm systems and Nate. Nate is rapidly weakening, but the remnants will track over New York City on Monday, so there may very well be flight delays.  Storm system #1 is racing northeast through eastern Canada and this was the system that affected the Plains and Midwest last week.  Storm #2 is now in the Pacific Northwest, digging southeast into the southern Rockies by Monday.  This system will then track northeast into the Plains and Midwest Monday night and Tuesday, bringing a big change to our weather. Let’s go through Sunday, Monday and Tuesday and track these big weather changes as storm system #2 moves in.


SUNDAY: The weather will be calm and comfortable today with highs 75° to 80°, a light wind and low humidity with abundant sunshine.  A weak cold front will slip in tonight ahead of quite a change.


MONDAY MORNING: Look how quickly things change as the storm system is dropping south through the Rockies.  Snow is likely in Denver with temperatures in the 30s.  KC will still have decent weather, with lows in the 50s, a clear sky and light wind.


MONDAY AFTERNOON: The system begins to head out in to the Plains.  A cold rain is falling from Nebraska to northwest Kansas with temperatures in the 40s.  It will be in the 80s to near 90° from northeast Oklahoma to southern Missouri. KC will see increasing clouds with temperatures in the 70s, 60s possible in northwest Missouri.


MONDAY NIGHT: The storm continues to get its act together and KC starts to see rain with an increasing north wind.  It looks like our area will be in the cold air.


TUESDAY MORNING: The cold, wind driven rain will likely be in our area with temperatures in the 40s.  This is not set in stone, but there is a strong trend in this direction.


TUESDAY AFTERNOON: The storm system is moving northeast through Missouri with our area stuck in the 40s, with rain and a brisk north wind.  Yes, we stay in the 40s all day Tuesday with wind and rain.  It is time to pull out the warmer clothes, but do not put away the shorts as warmer air will return by the end of the week.  Southeast Missouri may have severe weather as highs will be in the 70s and 80s with copious Gulf of Mexico moisture.

Now, the details of how much rain will fall in our area, in the colder air, is not set in stone as it could be .10″ to .50″ or as much as .25″ to 1″.  The exact track of the storm system is not set yet, so this surface map projection is subject to change which means the placement of the cold and warm air may shift by 50-100 miles.


Gary will update this blog Monday morning with the latest data on this big change.

Have a great week ahead.
