Cool Start To The Week, Frost Possible. Signs of above normal temperatures returning. :-)

 Southern sections of Manitoba will be experiencing a cooler than average next few days before potentially hotter and more unsettled weather returns, this blog will cover the outlook for Tuesday/Wednesday. There will be a risk of frost tonight as well. So details about this will definitely be brought up. 

Tonight: Overnight low temperatures will drop into the low single digits tonight, there is a possibility that some areas of southern Manitoba may see lows below 0C. High pressure will build south into northwestern Ontario tonight bringing a very cool airmass for this time of year. 

Tuesday: A southerly flow will return for the day on Tuesday with high pressure moving east, temperatures will return to normal daytime highs in the low 20's and mid 20's in western Manitoba. Below Normal values again will likely return on Tuesday night which is of concern because frost this time of year is not really expected, temperatures will drop again into the low to mid single digits. I do miss waking up to high temperatures in the teens. Fall is coming. 

Wednesday: A warm front will move in on Wednesday with a increasing amount of cloudcover, high temperatures will reach the high teens and low 20's. The warmest of the air will be in the southwest part of Manitoba. Wednesday night: A frontal system will move through on Wednesday Night, with a chance for showers and weak thunderstorms especially in western Manitoba areas. Overnight lows will drop into the low to mid teens on Wednesday Night, which is typical of lows in July or August. 

The Second half of the week: Warmer than average temperatures in the high 20's may be returning only on the day Thursday with some possible instabilty or thunderstorms, only for a brief period of time.  However it looks like the pattern may take a while to evolve as ridging in the summer time usually develops quicker, than this time of year which may push most of the warmth to next week as heat remains in Saskatchewan. Regardless warmer temperatures are here finally and I hope that we can enjoy the last little bit of the summer.
