Trouble in NorCal

Precipitation in California has exceeded all expectations. This is the time of year that the state gets most of its rain, and usually, they can expect a couple of good soakers and impressive snow totals in the Sierras when it happens. The rain doesn’t often fall as intensely in the Central Valley, in addition to the western facing hill sides, as it has this month. Redding, which is at the far northern end of the central California valley system, and called the “sunniest city in California”, was forecast to get some showers during our forecast on the 16th and 17th of December. Instead, it was the beginning of a grueling weeklong stretch of flash flooding and disaster just before Christmas. For our forecast period, Redding saw over an inch and a half of rain, which is quite a bit for anywhere, and certainly a lot for Redding, which has now received twice their monthly expected total for December, already one of the wettest months of the year in northern California. The forecast was fairly well handled on the temperature side, but the quantity of rain was surely underestimated. The Weather Channel had the top forecast.

Not quite Hot, but not as cold.

The headlines have all switched as we look ahead to Christmas. A lot of the country is going to see temperatures that are much warmer than normal, which is an about face after a particularly brisk beginning to the month. Our forecast in Hot Springs called for temperatures that were below freezing on Sunday and Monday morning. Fortunately, with the clear skies in the afternoon, temperatures were able to bounce back, and highs were warmer than the forecasts called for, even if they weren’t “warm” per se. Clime came away with the top forecast.

Failure to launch

It was a chilly weekend last weekend, particularly Sunday, in north Texas. We had a forecast for Sherman, and we knew that it was going to cool down, but clearly, we weren’t fully appreciative of how cold it was going to get. Accuweather had the top forecast for the weekend, and even they were 10 degrees too warm on the Sunday high of 37. Fortunately for them, that was the one really big issue they had, successfully navigating the rest of the forecast.

The first, not the worst

December came with a punch of cold air to the Upper Mississippi Valley, with the first subzero temperatures of the season arriving in La Crosse on the 4th. Fortunately, it wasn’t quite as chilly as the forecasts called for (except, ironically, Weatherbug). Unfortunately, it was a precursor to the vicious cold snap coming this weekend. Wind chills will easily eclipse -20 tomorrow morning. If you want to think warm thoughts, think about the warm fuzzy feeling The Weather Channel must have for nailing the forecast from back on the second. That should do it, right?

I can’t believe I missed this

I verified Raleigh earlier this week, and completely skipped over the verification for Providence. This was a busy forecast, with some rain coming into the area just as Thanksgiving was drawing near. There was rain on both Wednesday and a bit of a splash on Thanksgiving Day. As promised, the weather cleared by afternoon, which allowed locals to get out of the house and go for a walk to allow all that turkey to digest. The rainfall wasn’t universally included in the forecast, which really shuffled the standings. Weatherbug had the top temperature forecast, but fell back into a tie with Victoria-Weather – which makes me even more irritated I missed the verification! -for first place.

A long line of wet weather

We visited Raleigh at the end of November, which was in the midst of a soggy stretch that, frankly, is still ongoing. It’s been such a warm autumn, and the past few winters were so mild, it’s kind of bracing to see such a chill to the air as far south as the Carolinas. But we did indeed see some temperatures that were near freezing and didn’t even get out of the 40s for the first day of December. That particular day was colder than anyone had in mind, and certainly colder than anyone in Raleigh appreciated. If you want a cold forecast, Weatherbug is your place to be, and they secured the win on this occasion.

Birmingham’s Not-So-Stormy Weekend

Ahead of the Thanksgiving travel season, a storm system passed through the American southeast before petering out in the mid-Atlantic. There were some outlets that thought that it could lead to a bit of a severe weather outbreak around our forecast destination of Birmingham last Friday and Saturday, but fortunately, that didn’t come to pass. The whole feature was a bit messier than it could have been, and left some light showers in the region on Saturday as well as Friday, and didn’t bring the cold pool behind it that was in the forecast for some. It hit 80 last Saturday! Clime came away with the top forecast, thanks to a being one of the warmer forecasts on Saturday.

A breach of protocol

Generally, when I put together a verification, which this post is, I use WeatherforMe.com’s “closest NWS site” option. For Santa Cruz, that site is San Martin, 25 miles away from Santa Cruz, and crucially, on the other side of the Santa Cruz Mountains. Temperatures there at initial check were about 15 degrees warmer than forecasts, and another 5-10 degrees colder for overnights. I decided to opt for the road less traveled, and used a MADIS site in town. It was still warmer than expected, but not as egregiously so. The arrival of a feature on the West Coast had effectively drawn the low scud away from the coast and allowed high temperatures to infiltrate. High temps on the 8th and 9th were both warmer than anyone had in the forecast, but low temperatures lined up. Accuweather had the best forecast. Would they have if we verified against a completely different climate?

A beneficial deficiency

The separator for our forecast today was one that I’m not sure I would have imagined. Temperatures in Greeley were very responsive to the wind, it seemed, which meant that the response to the clear skies was not to be had. On the 5th, temperaturs stopped dropping around 2AM, which meant that outlets with warmer lows ended up cleaning up. WeatherNation, therefore, cleaned up, earning a comfortable victory.

Not so spooky season

At the end of October, the North Carolina Coastal Plains saw quite a bit of rain. Fortunately, it started to turn off right before Halloween. In Burlington, there was a trickle on the 30th, and most of it cleared out before the majority of people were awake. Then, on Halloween, it was even nicer, with clear skies and temperatures that rebounded into the 60s. A little chilly for an evening of trick-or-treating, but surely a fair sight better than many were probably expecting. Unless they were looking at the forecast from the Weather Service or Weather Nation, I guess, because those two knocked this forecast out of the park.
