They've finally pulled the trigger on a WWA. A little surprised it wasn't issued sooner, given the robust anafrontal precipitation shield.

Well defined cold front just entering into Pennsylvania.

Up to 66F at PIT. If we can hit 70F, that would be the fifth 70+ day of the year already, which would match 2025, 2000, 1946 & 1876 for most on record. Little bit of weather trivia there.

Has ramped up quite a bit since that map. Duquesne is up to nearly 90k out alone.

No power here.

Hopefully, this wind dies down soon.

Classic spring weather in Pittsburgh. Look at these ups & downs. Taken literally, the GFS has Monday 41F warmer than Tuesday - though I don't think this is properly accounting for midnight highs & lows (non-diurnal temperature ranges).

Thanks, Don. I agree there's a UHI component as well, but it's not impacting the trends. Whereas Phoenix has warmed at about .6F/decade since 1896, NCEI has the State of Arizona warming at about a third of that rate (0.2F/decade), so it's not like they are just using Phoenix numbers to calculate the official trends and departures. By the way, Death Valley - with a population of, checks notes, zero - has 4. But really 6, as the numbers for November & December in 1913 & 1914 are clearly erroneous. The huge surpluses were driven by implausibly high temperatures with impossibly small diurnal ranges that make zero sense in winter in Death Valley. Ignoring those months, it's 6 of 12.

Some food for thought:
