Temperature contrasts (hot, warm, record, days)

[nei]

Yesterday was one of the weirder weather days I experienced. Morning was some of thickest fog I've seen in a while and in the upper 50s. Drizzling slightly. Stayed like that till around noon. In the next few hours (12:30 to 3 pm) the fog and clouds cleared and it warmed to 82°F, with a strong south wind.

In Boston at the same time, it was 54°F, with a strong wind coming off the Atlantic. Boston is 85 miles to the east of where I was.

Have other people seen a temperature difference (28°F) that large in a short distance? I know it's common off the Pacific Coast, but I didn't expect a big contrast off the Atlantic. I suppose it would be the best of year for this to happen, since the ocean is still quite cold, but the spring sun is quite strong, heating land easily.

well it depends if a cold or warm front passes or not.. without a cold/warm front passing.. I don't think we have that much extreme temperature variation here between two places.

I don't know specifics, but last week when we had hot weather and an easterly wind the east coast widely had mist/fog and highs of 12C, whereas 50 miles inland (or perhaps less) a lot of places had 25C or more. Happens every year, just not normally to the same extent. And I didn't see it myself but I posted recently about Altnaharra in Scotland once being -22C in the valley and +3C on the mountaintop 1000 metres higher up and supposedly only a few miles away. Also, I've mentioned before about us being at -6C whereas a suburb just outside London was -20C at the same time, which I'd guess is 15 or so miles away. You'd never get that in the daytime though.

Here's a contrast. Yesterday in McAllen Texas, the temperature was 102. This morning, the thermometer just hit 32 in Hereford, Texas. That's over 100 and below freezing, in the same state, within the same 24 hour period. I don't think that happens very often in a state that has no mountains.

Here in Victoria TX, we tied the record for the date yesterday with 97, and this morning it's a bone-chilling 58. A 40-degree swing is pretty common in the mountains or desert, but pretty unusual down here at sea level. Yesterday, in about 8 hours, our dew point dropped from the low 70s to the mid 20s.

I love those wild temp swings! I live in a place where we have 15-20 degree difference regularly between TR and Manitowoc (7-10) mis. and sometimes 30 degrees 10-20 miles inland. This isn't a rare situation it happens often especially in Spring, Summer, Fall not as much in the winter.

If a front goes through then the swings are way more dramatic. I get a kick out of it though as bigger stores are in Manitowoc going to Lowes, Menards dressed in jeans & sweatshirt and folks there are in shorts and tee shirts!!! They say oh, you must live in TR or Trivers as the locals say.

One day last summer 90's in Green Bay we had 50's. I went down to the lake to see the waves, car pulled up, 4 college kids got out, were they surprised!!! Shorts, tank tops and flip flops, what a hoot!

I still remember that one day, it was in 2000 (or maybe 1999?), where we had a morning typical in winters - foggy, cool and probably 13C. The afternoon then became searing hot, 38C (something around that). Very strange, especially for Sydney - I would think that SoCal experiences this?
