Good Sunday bloggers,

I hope everyone is doing well and staying healthy. This is quite a time in our history and we are all in it together. Walks outside are allowed as long as there is social distancing, but the weather is making it tough. We will have some nice weather hours and days in between storm systems. We are tracking three storm systems the next 7 days. The first one is today, the second one will affect Monday night and Tuesday and a third will arrive Friday into Saturday. You can see them all on the satellite image from early Sunday morning.


So, let's go through this.

SUNDAY: Rain showers and drizzle will continue all day ending tonight. Highs will be around 40. Snow will be likely across far northern Missouri and there could be some minor accumulation on grassy surfaces north of Highway 36. Total rainfall with this system will be .25"-.80".


MONDAY: After the rain showers and drizzle end tonight there will be a chance for dense fog. Lows will be 35-40. Highs Monday will reach 50-55. If the clouds stay thick all day, we could see highs stuck in the 40s.


TUESDAY: The second storm arrives Monday night and exits by Tuesday evening. There will be widespread rain and thunderstorms into Tuesday afternoon before tapering to rain showers and drizzle. Lows will be 45-50 with highs 50-55. A new .25-1" is possible.


WEDNESDAY: Right now this looks like the best day of the week as highs reach 65-70 under a partly to mostly cloudy sky.


RAINFALL FORECAST THE NEXT 7 DAYS: This might be a bit overdone, but when you add up the three storms systems the next 7 days, 1.50" to 2.50" is possible. Does all of this rain mean another year of major Missouri river flooding?


One of the main things that set off the major flooding last year was a 2" to 4" rain storm on top of a 10" to 40" snow pack across the upper Missouri river basin March 10-15, 2019. This released an overwhelming amount of water into the river system in a very short time.


This year there is much less snow pack over the upper Missouri river basin. So, this would normally mean there is less of a chance of major flooding on the Missouri river this year. However, many levees are still not fixed, so it is going to take much less water to create issues. We will have to watch this closely as we are in somewhat of a wet pattern.


Have a great week and stay healthy.
