I stumbled across this string of Low Temp Records recorded by WFO PAH in 2004 and I don't remember it happening. Or at least not why.

August 7 -- 51
August 13 -- 48
August 14 -- 46
August 15 -- 49
August 16 -- 48
August 17 -- 51

It's certainly not uncommon to have a new Low every once in a while, but it seems fairly odd to see so many clustered together. Normal lows for August are around 70 or so.

It was a mass of cool dry air that went all the way down to the northern Gulf Coast and also served to punt Hurricane Charley toward the Florida peninsula instead of the usual Mobile, Alabama target for that kind of cyclone.

On this topic, I would be curious to see what the weather pattern was during the spring/summer of 2004 country wide.

Here is a 500 mb Geopotential Height map for the Northern Hemisphere.



Notice the ridging over Alaska and Arctic during the spring (March to May). The ridging is still over Alaska in the summer (June to August). There is a trough over US and Canada in the summer, that is a factor for allowing many hurricanes to hit the US in the 2004 season.

How does this compare to the current pattern this year?

This is my opinion but the pattern this year seems to be similar so if anything expect more cold shots in the Ohio valley and midwest and don't be surprised if another hurricane hits land based on this pattern

Here is 2014.


Spring 2014 is similar to Spring 2004. Both have troughing over Northern Canada, while there is ridging over Alaska. However, Summer 2014 is different from Summer 2004. There is troughing over Alaska, while there is ridging over Northeast Canada and Greenland. Troughing over Alaska indicates a positive East Pacific Oscillation (EPO)

Yes, that was a wonderful August cool period. I think we set record lows five days in a row....longest strech of consecutive record lows I believe. With the continued troughs in the east it is possible we could see another repeat of August 2004 in 2014.....MGC

The first thing that comes to mind when I think of August 2004 is September 2004 when the pattern quickly made a 180° turn around and strong Western Atlantic/East Coast riffing allowed two formidable and rememberable hurricanes to strike Florida's east coast, which is a very rare occurrence (even just to get one hurricane strike on Florida's east coast).
