Watching the Tropics
According to NOAA's National Hurricane Center, there is an area of interest off the southeast coastline that has a medium chance of tropical formation over the next 5 days. It doesn't look all that impressive on the IR Satellite loop from Saturday, but it will continue to bring areas of heavy rain to parts of the Bahamas over the coming days.
Watching the Tropics
According to NOAA's NHC, the area of interest mentioned above has a medium chance of tropical development over the next 5 days. It should stay fairly stationary over the coming days, so areas of heavy rain can't be ruled out for landmasses near this area of interest.
Large Wildfires & Smoke From Saturday
The map below shows several large wildfires burning in the Western US and across Canada. Hazy skies and unhealthy air qualities continue in many locations downwind of these fires. Note that dense smoke has made it all the way to the East Coast and even into the Western Atlantic.
Smoky Skies Midday Sunday
According to NOAA's HRRR weather model, the smoke analysis for midday Sunday shows more widespread smoke across the northern tier of the nation, including Minnesota. Skies will likely remain hazy with the potential of unhealthy air qualities in some locations. Interesting to see wildfire smoke as far south as Florida.
Minnesota Drought Update
According to the US Drought Monitor, nearly 20% of the state is now considered to be in an Extreme Drought, which is up from the 4% last week. Keep in mind that this is the first time any part of MN has seen Extreme Drought since April of 2013. 72% of the state is in a Severe Drought, which is up from the nearly 52% from late week. Moderate drought covers much of the Twin cities.
Precipitation Departure From Average Since Jan. 1st
It has been a warm and dry year so far with precipitation running well below average across much of the region. Here's the precipitation from average since January 1st, which shows several locations running several inches below average. The Twin Cities is nearly -5.25" below average precipitation since the beginning of the year, which is the 27th driest start to any year on record. Milwaukee is nearly -9.00" below average, which is the 3rd driest start to any year on record.
Sunday Weather Outlook
The weather outlook for the Twin Cities on Sunday shows hot, dry and hazy weather conditions in place through much of the day. Note that the MSP Airport has seen (18) 90F days so far this year, so Sunday's high of 93F will make it the 19th day with highs in the 90s so far this year. The average number of 90F days at MSP is generally around 13, last year we had 12.
Not As Humid Sunday
Friday was a very sticky day with dewpoints in the 70s, which is considered to be Tropical. Note that dewpoints will be nearly 20 degrees lower on Sunday, which means that there will be nearly half as much water in the atmosphere than there was on Friday.
