6-26-19 Hazardous Wx Blog: Discussing year to date precipitation in the Midwest and a brief look ahead. N.

Good afternoon!  Thanks for checking out today’s edition of the Hazardous Weather Blog!  Wanted to discuss how wet it has been year to date across the Midwest, with a brief look ahead!  

The year to date rainfall has been nothing short of incredible, particularly from Kansas to Missouri to Ohio, with a few locations already having reached the normal for the entire year.  There are literally locations where if it didn’t rain a drop the next 6 months would average out to normal.


How does this compare to “normal” for the date?  Here is the precipitation departure for this point in the year.  Parts of southeast Kansas are nearly 30″ ABOVE normal.  Wild.  Note that almost everywhere is wet year to date, aside for portions of North Dakota and northern Minnesota, where there are actually drier conditions, and a drought in northern North Dakota.  

Let’s strictly look at June.  Some areas from eastern Kansas to southwest Ohio have already received 12″ of rain this month.  

Here is the precipitation departure for this point in June.  Parts of Iowa have managed to stay drier than normal this month, but the combination of the wet spring up to this point and the cooler conditions have limited the Growing Degree Days and have not allowed soils to dry out substantially.  Parts of the Lower Ohio Valley are 9″ above normal.  

Here is a look at month to date precipitation for Indianapolis:

Indy has picked up 7.51″ so far this month.  That is 3.97″ above normal month to date.  For the year so far, Indy has had 29.15″.  The normal for this point is 20.94″, so we are 8.21″ above normal!  Indy averages 42.44″ during the year, so we have already seen 69% of our annual rainfall.  

Other interesting tidbits for Indianapolis:

-Last fully dry week was 36 weeks ago in mid September. 

-Out of the past 25 weekends, only 4 of those have not produced measurable precipitation, or 16%.  

For the areas that have been the wettest, that is where we find the driest conditions from now through early next week.  A welcomed sight.  A large ridge of high pressure brings widespread heat for the first time this season, and also forces the storm track to shift north.  Here is the precipitation from normal forecast now through early next week.  Brown=drier than normal.  Green=wetter than normal.

Unfortunately, this drier pattern is short-lived for most as the upper flow looks to gradually flatten with more of an eastern ridge, and wetter conditions returning north to south over the Ag Belt in week 2.  We have more daily in our long-range reports.
