July 2014 General Discussion

Only a trace of rain here.

 

So DTW dropped to 51F this morning...missing the record by 1F. And of course, there was NO intra hour low (like there is almost always a 1-2F intra-hour high temp), and there was also a mysterious missing hourly ob last night. I suppose the other way to look at it is that it was colder than forecast anyway. Todays mean temp of 63F is a record low for the date, however. Yesterdays record low mean temp was set in 2013. A taste of Fall two consecutive years at the end of July. (the difference being that this July was peppered with numerous tastes of Fall). This July should place somewhere between 7th and 10th coldest on record, pending the next two days temps.

0.75" of rain in the LAF this evening. First cells that passed through had some decent gusts...nothing special, mind you. But it doesn't really take much this year here, for it to be somewhat exciting.

Wow, only 0.21 in my bucket. After last nights *fiasco* I suppose you need to cash in on something.

Lake Effect rain going on right now in July north of Buffalo. 2-3 inches already with hail in some embedded storms. Despite diurnal influences the band seems to be remaining strnog. I've never seen Lake effect rain in July in my life. This year is crazy! NWS calling for more Lake effect rain tonight and tomorrow.

 

THE AIRMASS IS STILL COOL ENOUGH ALOFT TO SUPPORT LAKE ENHANCEMENT AS
WELL...ESPECIALLY DURING THE MORNING WHEN LAKE INDUCED CAPES WILL
RUN AROUND 1000J/KG WITH EQUILIBRIUM LEVELS AROUND 30K FEET. THE
ADDED LAKE INSTABILITY WILL PRODUCE A RELATIVE MAX IN SHOWER
COVERAGE OVER LAKE ERIE LATE TONIGHT...WITH THE LAKE ENHANCEMENT
DETACHING FROM THE LAKE AND SPREADING EAST ACROSS THE AREA EARLY
THURSDAY WITH THE PASSAGE OF THE MID LEVEL SHORTWAVE. THERE WILL
ALSO BE SOME LAKE ENHANCEMENT FOR A FEW HOURS EAST OF LAKE ONTARIO
AS WELL. GIVEN THE IMPRESSIVE LAKE INSTABILITY...STEEP LAPSE
RATES...AND STRONG MID LEVEL FORCING SCATTERED THUNDERSTORMS ARE
ALSO POSSIBLE.

The Gaylord record is a lock, today had a mean of 57F, tomorrow will probably be below 61.4.

 

Its a lock, coldest July in Gaylord history.

 

The pattern that has been locked in place since last fall, looks to be locked in for the winter. Don't expect a big LES season, but whatever falls should stay and pile up.

Another morning in the 40's, 49 was my low.  I think it's the 11th for the month.... for sure hasn't felt like July.

 

here's what an APX met told me:

 

As for lake temps, about the only correlation we note is a tendency for the lakes to freeze quicker, provided of course we have a nice long stretch of colder weather to begin the winter season (which we just might given the pattern this year). Outside of that, the lakes will still be plenty "warm" by the time Sep/Oct arrive to give us a nice bout of early season lake snows, though it may take slightly cooler 850mb temps initially to get the better lake response.

Todays high/low was 81F/54F at DTW. So basically, the low was cooler than expected and the high warmer (forecast was 78/58).

 

July 2014 will finish with a mean temp of 69.9F, which ties for the 8th coldest July on record! This in a year with the 6th coldest Jan, 15th coldest Feb, and 11th coldest Mar. Very impressive, especially in the UHI age. Looks like 2012s other shoe has dropped.

 

Coldest Julys at Detroit - since 1874

1.) 1891 - 67.1F

2.) 1992 - 68.8F

3.) 2009 - 68.9F

3.) 1967 - 68.9F

5.) 1971 - 69.6F

5.) 1875 - 69.6F

7.) 1920 - 69.7F

8.) 2014 - 69.9F

8.) 1924 - 69.9F

8.) 1884 - 69.9F

10.) 2000 - 70.2F

 

Todays overperforming high meant we eeked out an 80-degree day, so July 2014 will finish with 14 of them, which is the 9th least on record.

1.) 1891 - 9 days

2.) 2000 - 10 days

3.) 1920 - 12 days

4-8.) 1884, 1895, 1924, 1992, 2009 - 13 days

9.) 2014 - 14 days

 

The month saw just one 90F day...and so far just two on the year.
