Scattered Showers & Storms, Then Cooler...

Good Morning!


The scorching heat that baked us Trolls yesterday has once again retreated back southwest for the time being, though it is still lurking nearby.  Several records fell throughout the area yesterday, with air temperature and heat index values in triple digits.  You can already feel the difference from yesterday,  most places were pushing 90 by 10AM.  As I write this today at 10AM, Hillsdale, Coldwater, Adrian and Battle Creek are the warm spots, posting 78 or 79 degrees.  We've got some ground to cover today so let's get in there and pop the hood...


TEMPERATURES:  The good news is that we shouldn't see any triple digits, either for heat index or air temperature today.  The bad news, it'll still be warm and damp for awhile.  Temperatures should return to the low or even mid 90's today, until a front that is stretched pretty much east to west across lower Michigan drops all the way through from the north.  That will cool us back into the 80's once that occurs, but for now, it's stalled out, pretty much straddling the north and south zones of the blog. (If you aren't sure what zone you're in, look at the temperature readouts on the left and find the biggest city shown near you.) We'll see mid to upper 80's after this front gets through here.


RAIN:  You can see where the air masses are right now over us, as there's some shower and thunderstorm activity on the warm side of the boundary.  The south zone of the blog is bone dry for now, with the north zone getting some good, beneficial rain that is badly needed.  Here's a look at the Grand Rapids NEXRAD radar...

The south zone is SLOWLY starting to get in on the action, with a couple of showers and storms firing in Branch and Hillsdale counties.  These storms are pulse and scattered in nature so coverage is still fairly sparse and not the good soaking rain your lawns and fields would love and need right now.  The National Weather Service is only predicting about a half-inch of rain on the high side for the next five days...


5 Day Precipitation Forecast
That looks about right, but given the storm tracks so far this season, I'm inclined to halve that to a quarter-inch for the south zone and leave it as is north.  I say inclined because we have to talk about...


SEVERE WEATHER:  I know it may wrong, but I am GLAD to see us in a "slight" risk area for severe weather today.  A good, wet thunderstorm or two will help us out a lot.  The other side of that coin is that it's so dry, cloud to ground lightning could spark a wildfire.  Today and tomorrow we have a shot at some thunderstorms, here's a look at the forecast maps from the Storm Prediction Center, valid at 8AM as always...

Storm Prediction Center Day 2 Forecast
The main threats from these storms today will be damaging wind and hail, nothing tornadic is anticipated.

Here's the forecast for Jackson and surrounding communities including Parma and Leoni Township:


For today, scattered showers and thunderstorms through about 1 PM, some could possibly become severe, then partly sunny with a high near 93, winds SW turning NE 5-10 MPH.  Scattered showers and storms could re-organize and fire during or after the evening commute.


Tonight, scattered showers and thunderstorms early, with cloudy skies, nighttime lows roll back to 65, winds ENE 3-8 MPH.


Thursday, cloudy skies to start with a chance of a lingering shower or lonely thunderstorm, then becoming mostly sunny, high 82, winds becoming N 3-8 MPH.


Thursday night, clear and cooler, perhaps a couple of passing clouds, low down to 59, winds N 3-5 MPH.


Friday, partly sunny, seasonable, high 83.


Saturday, periods of clouds and sunshine, continued seasonably warm, high 85.


Sunday, partly cloudy skies, a bit warmer, a chance of an isolated or widely scattered shower or thunderstorm, high 88.


Monday, increasing cloudiness as the day progresses, widely scattered showers and a roaming thunderstorm cannot be ruled out, high 89.

There's a look at your forecast for the next six days, I do hope that you have a great hump day Wednesday!  Blessings.

Twice Baked Troll*...

Good Morning!


*TROLL - Teasing, joking name given to a Michigan resident that lives in the Lower Peninsula (under the bridge), typically by someone that resides in the Upper Peninsula.


Back into the oven we go today here in South Central Michigan.  Every county in the blog is under some sort of heat alert, and temperatures will easily top 100 in many places today.  The coolest spot showing on the blog is 84 degrees in Jackson as I start this post.  Most places are already up near 90.  Let's get in and take a look under the hood to see what's going on...


TEMPERATURES:  I could just say hot as the dickens, then cooling and be done with it really.  As stated in earlier posts, temperatures should fall in the 95-103 degree range with heat index values from 101-110 today.  I don't need to go into detail as to what you need to do to cope with the heat as this is not our first rodeo in the oven this summer.  High pressure and the clockwise flow around it bring hot air in from south of us.  The only good news is that at least in theory, this should not last too long.  We should see some relief tonight and into tomorrow, as temperatures fall back into the more seasonable mid 80's.  The cold front that is north of us riding the US/Canada border is expected to sag south and break this heat.


RAIN:  If the cold front sags south and breaks this heat as forecast, we'll see about an even money shot at some showers and thunderstorms late tonight and into tomorrow.  At this point, given the conditions, I would expect any storms that can form to be of the pulse hit and run variety, so no, there is no drought-buster in the offing.  Many places will continue to brown over.  The National Weather Service thinks we'll pick up about a half-inch of rain over the next five days, and that looks about right, bear in mind it will be hit or miss.  Here's that map.
5 Day Precipitation Forecast
SEVERE WEATHER:  No severe threat to speak of right now, just a general risk of storms for all three days, perhaps a slight risk today maybe into Livingston County, but that's about it.  Honestly, I would almost take a severe weather event, because that would increase our rain chances, but the flip side is that it's so dry, a lightning strike could spark a wildfire.  Plus we are at the point now that just one event will not erase the damage that has been done because of the lack of moisture for the season.  Here's the Day 1 outlook from the Storm Prediction Center...
Day 1 Severe Outlook
Temperatures are running in the upper 80's or better across the entire blog area, no rain on radar, you can see the clouds associated with the cold front on the visible satellite image...


Visible Satellite Image, clouds north are where the cold front is when the image was captured.
Here's the local forecast for Jackson County:


For today, Heat Advisory in effect until 8PM EDT, more sun than clouds, unseasonably hot, high of 102 with heat index values approaching 110.  Winds SW 7-14 MPH.


Tonight, periods of clouds and stars, still warm, nighttime lows only roll back to 71, winds turn NW 5-10 MPH.


Wednesday, mainly cloudy with a few peeks of sun, a widely scattered or scattered shower or thunderstorm is possible, cooler, high 87.  Winds NE 5-10 MPH.


Wednesday night, cloudy skies, a few breaks for stars, cooler, low of 67, winds NE 3-8 MPH.


Thursday, more clouds than sun, cooler and more seasonable, high 83.


Friday, a mix of clouds and sunshine becomes mainly sunny in the afternoon, continued seasonably warm, high 82.


Saturday, clear skies, pleasant, high 84.


Sunday, mostly sunny skies, warm and summery, high 85.


There's a look at your forecast for the next six days.  I do hope you have a great Tuesday.  Be careful in this heat!  Blessings.
