Riding this hotness

These well below normal last few days have knocked down the monthly temperature departure at MDT to just +1.5 through yesterday. It’s hard to believe with the two heatwaves that we had earlier this month, but outside of that, it’s been a fairly pleasant July in terms of temperature. The severe weather has been the worst part for many of us. @Mount Joy Snowman it’s time for your back of the envelope calculation for MDT’s final monthly departure estimate. Do you think there’s a chance that a near normal month goes in the books when all is said and done?

A cool 60 degrees after a light rain of about 0.15. I like seeing no heat wave in the forecast

Gorgeous morning to play a softball tourney

Messy setup.

Looks like might be congrats Dendy with the heaviest rain Tuesday

Taunton's rental unit for next week? He doesn't have much luck with vacations.

I'm down here just inland from Fenwick. Light shows and clouds here this morning. Hopefully it clears up this morning.

Nah, I will stay local. Worcester - eight straight days of below normal temperatures and temperatures in the '70s. Remarkable considering peak summer. The hot crowd can't win for losing.

thank you, I appreciate you keeping us posted about MBY delightfully refreshing sub 60 morning out there for a run, or just drinking coffee

Yep light rain just up the way from you in Lewes this morning.

Models hinting at a rainy cutoff low this week. Details as to where the heaviest convection focuses will have to wait. Since the timing of how soon the upper low cuts off and captures the surface low vary from model to model.

Was just about to post this. Don’t expect this, although NAM had this on and off the other day. My friend might be pissed since we left his boat out without the cover…

Since you’re tracking other states than where you live for daily and monthly temps..could you check Boise, Idaho and Santa Fe , NM and post please ?

53° / 51° another cool start to what it looks like a beautiful day. Mild up beginning the second week of August? Hartford now stands at 0.4 above average for the month. What happened to the hottest month ever?

Rain in OC this am. Short term models last night were too far south with the rain.

OK lets see what the raw data says. After all bias adjustments are based solely on raw data. If the the steel mill impacted the Coatesville station it would be reflected in the raw data and in the NCEI bias adjustment. Below is a plot of Coatesville 1SW minus West Chester and the Coatesville bias adjustment (right axis). A station change at either Coatesville or West Chester causes a sudden change in relative temperature of Coatesville and West Chester. While a growing steel mill or an urban heat island in one of the towns would cause a gradual change in the difference between the two stations. There are many large sharp changes in Coatesville's temperature relative to West Chester. These are all station changes. There is no indication of a gradual long-term trend so a large change in the steel mill impact can be ruled out. Station changes are the primary cause of Coatesville's (and West Chester's) cooling. The Coatesville bias adjustment (right axis) tracks the raw temperature data at Coatesville and West Chester closely, capturing the each wide swing due to station changes. The only exception to the close tracking is when West Chester had station changes: 1915, the 1920s, the 1960s and with the West Chester move in 1970. Both stations start out at about the same temperature in the 1890s. Between 1894 and the 1960s, most of the chart movement is due to Coatesville station changes as West Chester experienced relatively minor station changes. After 1920 Coatesville cools relative to West Chester. The change is anything but gradual with several large swings due to station changes. From the late 1940s to the late 1950s Coatesville is 2F cooler than West Chester. The rural Doe Run Road site is the coolest Coatesville station location. Coatesville warms by roughly 0.5F around 1960. After 1960 the main station changes are at West Chester, ending in the 1970 move which cools West Chester to down Coatesville's level. Note that station changes can be warming or cooling, but on balance both stations cooled significantly over the period due to station changes. This exercise is another feather in NCEI's cap. The Coatesville and West Chester raw data shows that bias adjustments are needed and accurate in Chester County. No surprise if you have been reading the thread.

54 degrees this morning. Enjoy the weekend!

The only thing I disagreed with was taking Rogers out at 88 pitches. But to be fair...Garcia didn't make a bad pitch; it landed way below the zone and the dude somehow golfed it. But that only tied the game; the blown opportunity in the 9th, stupid error in the 10th. Core issues once again that have been going on before this year, smh

Getting intrigued for Monday.

Warm how? Am I going to need an air conditioner?

Most strong Ninos produce moisture,as to what happens this winter is surely uncertain,i still think NOV could dry out,severe Dec cold Jan and Feb,March are crap shots,but probably AN,thats just my opinion and surely might not be right

Hearing the first katydids of the summer.

The low of 51 yesterday was the first time PIT has been below 54 in July since 2014. It got below 54 at least once every single July from 1976-2003.
