Even Cooler Air Arrives in Indianapolis

Yes folks! It is July and it is summer. In fact, we are suppose to be in the "Dog Days of Summer" which is basically the hottest period of the year but unfortunately it doesn't feel that way outside. We are starting to lose solar energy, the days are starting to get shorter and the nights are becoming longer.
Here's the list of highs and lows observed this week:

SUNDAY: High 83 Low 66
MONDAY: High 83 Low 69
TUESDAY: High 91 Low 66
WEDNESDAY: High 77 Low 58
THURSDAY: High 79 Low 57
FRIDAY: High 79 Low 60
SATURDAY: High 78 Low 66 (OBSERVATIONS THRU 8PM)

COOL AND BEAUTIFUL SATURDAY
The passage of a cold front accompanied by a wind shift kept temperatures once again in the 70s Saturday afternoon. There was some rain overnight into daybreak hours (0.59") but with "FROPA" pushing skies cleared up a little bit allowing for some sunshine. You can see the fair weather cumulus clouds that was around earlier this afternoon in the photo to the right. This a 4pm snapshot of the East Skycam from the BAM Chase Team from Greenwood, Indiana.

SUNDAY'S UNSEASONABLE COOL WEATHER CHALLENGES WEATHER RECORDS
Winds are coming in from the Northeast and if we are under clear skies overnight this will help drive temperatures down in record territory. The morning low for Sunday is 54° which was originally set back in 1971 but later tied in 2004. Many models want to take the low down into the upper 40s, though possible, I don't think that will happen. Lows should flatten out in the mid or low 50s. I'm going with a low temperature forecast of 53.
Sunday afternoon we will be under partly or mostly sunny skies. Afternoon temperatures should reach the lower 70s. This will be close to the record for the lowest high temperature of 72 originally set back in 1925 but later tied in 1928. In order to break that record we will need to be lower than 72° or at 72 to tie. If we go 73 or above then the record will continue to stay as is.

COOLEST BRICKYARD 400 IN 19 YEARS!
I should also mention that Sunday is the day for the 19th Brickyard 400 held at the Indianapolis Motor Speedway. Watch out for travel restrictions or road closures. This could potentially be the coolest brickyard in history or the second one. When it first began back on August 6, 1994 the high was 73° and the low was 50°. Nearly a carbon copy in store for us this year. These cool temperatures are more typical for mid to late September.



SLOW CLIMB IN TEMPS FOR THE WORK WEEK
MONDAY: Temperatures will rebound but still fall short of 80s. We'll start again with lows in the 50s and afternoon temperatures should make it up to the upper 70s under mostly sunny skies.

TUESDAY: Temperatures will be about the same as Monday, if not a few degrees warmer! We will need to watch for the next system rolling through late date that offers a shot at showers or thunderstorms.

WEDNESDAY: The threat for more rain remains, or rather ending before lunch time, which comes from Tuesday's storm system. Temperatures will continue to slowly climb possibly finally making its way back into the 80s!

THURSDAY/FRIDAY: Its the first day of August and you can expect more of a normal August 1st day with temperatures trying to make a run toward the mid 80s. Same as Friday as well. The warm air will be brief though as a weekend weather disturbance arrives bringing in our next storms chances.
NOTE: My 8 day weather outlook is posted at the end of the blog.

WEEKEND STORM CHANCE
GFS brings in a soaker Saturday, August 3rd. May actually come in late Friday night lingering into Saturday. Watching for any thunderstorm development with this system. Some cooler air may try to push the warmer air out. Lots of details to iron out and more model runs to watch. It may be overdone but for now, I've included it in my 8 day. I've also trended a little cooler with my temps that day. May be hard to press 80s if this verifies so I went upper 70s instead. Standby, more updates to come on this in a future blog.



THE DEPARTURE FROM NORMAL (ABOVE NORMAL) GAP IS CLOSING IN
The weather pattern has been rather soggy for those in Southern and Western Indiana. Central Indiana is okay for now but most areas are getting below normal for the season and are below normal for the month. Back in May, some areas were almost 6" above normal for the year but since then the number has come down. We are now 3" above normal in Indianapolis. Those in Eastern parts of Indiana, things aren't looking too great. For the 1st time since the winter, these areas (which equates for 5% of the state) are abnormally dry. Shelbyville is over 8" below normal for the year. I've updated my rainfall chart below. Here's also a look at the latest drought map.

ATLANTIC HURRICANE SEASON TYPICALLY PICKS UP IN AUGUST
For those not in tune to the Atlantic Hurricane Season, currently we are on the 4th named storm. This is former Tropical Storm Dorian. Dorian has been struggling to stay organized in open waters fighting wind shear and dry air. As of 5pm, Dorian has degenerated into a tropical wave still located well away from land. It is positioned about 550 miles East of the Northern Leeward Islands and rapidly moving westward at 24 mph. The National Hurricane Center is no longer issuing public advisories on this storm system. The tropical rainstorm may impact the Carribeans & Bahamas Sunday-Tuesday.
The tropics typically become more active during the months of August and September. Last year, during those two months there was 10 tropical storms, of which 7 became hurricanes. 200 people died last year directly to these Atlantic storms and an additional 155 indirectly.
