A very merry forecast

Ryan Henning Leave a comment

On Christmas Eve, while all the children were snug in their beds with sugar plums dancing in their heads, we were stirring with a forecast for Sebastian, Florida. It made me pine for the years I spend in Florida, as highs were near 80 on Christmas and the day after, with barely a cloud in the sky. With the way this month has gone, it nearly rates as a Christmas miracle, but Victoria-Weather had the top forecast for Sebastian.

Winter blows in

The beginning and middle of the month of December were rough, to say the least. The second major system featuring severe weather started in the northern Plains, and reached the Great Lakes by our December 16th forecast time in Grand Rapids. There was a gust of nearly 60mph, even outside any precipitation on Thursday the 16th. Temperatures, which started in the low 60s on Thursday were ready for a decline, dropping 35 degrees for Friday. Even though the weather was bad, forecasts were generally good. The Weather Channel had the best temperature forecast, but Forecast.io drew level as they were one of only two not to have rain in the forecast.

Missing the drop

The same system that brought such devastating weather to the Ohio Valley was also responsible for putting a chill in the mid-Atlantic. When we forecast for Lynchburg almost two weeks ago, nobody anticipated the plummeting temperatures on the evening of December 12th. We all more or less suspected a non-standard day, but not THIS non-standard. It was 27 degrees by the time the 12th turned to the 13th, and forecasts busted across the board. The fast arriving front also prevented record highs on Saturday, which was against the grain for some outlets as well. Forecast.io ended up collecting the wind, mitigating their losses with a cooler forecast.

The morning lows in Asheville last week were out of control. After a couple of clearer than expected evenings, the low temperature dropped well beyond expectations, especially on Saturday, where the morning chill was in the mid-30s. Rain never came to the North Carolina town, and Forecast.io, was the only dry forecast in the house, securing victory for the day.

The Prize

Many of the nation’s top weather institutions are in Norman, outside of the city of Oklahoma City. The Storm Prediction Center, National Severe Storms Laboratory and the University of Oklahoma, one of the best schools for meteorology in the world all call Norman home. Most meteorologists I know have, at some point, passed through the area. This is a forecast that strikes to the heart of meteorology, and an extra pat on the back for the winners for the day, Weatherbug (not headquartered in Oklahoma City, by the way). The verification was quite remarkable, in it’s own way. The Saturday high was lower than all forecasts, while the low was at the top end of forecasts. On Sunday, the reverse was true, with a warmer high than anyone called for, and a colder low. Still and all, a decent enough forecast, and we have not embarrassed ourselves on these hallowed grounds.

Back on track

The verification for Kennewick sure was humbling. It wasn’t the case in San Antonio, however, as departing clouds and a little bit of exiting drizzle left the city with mild, almost cool conditions for a couple of days… just like we expected. Temperatures were a hair lower than what was in the forecast, but the high of 71 both Sunday and Monday was pretty close to what we all expected. The Weather Channel and Accuweather claimed a shared victory.

Nice Job, Good Game, Better Luck Next Time

Was our forecast for Kennewick the worst we have ever done? No, I wouldn’t say that. This is a solid D effort all around, and consistently so, across the board. D- though. Ahead of a cold front, upslope flow socked Kennewick in last Monday, keeping temperatures nestled in the mid to upper 30s, with nary a chance to escape. Then, when the front came, to the shock of all participants, the moisture did “traverse the Cascades” and brought a little bit of light rain to the area. When the cloud cover cleared, and the sun came out on Tuesday, all while the upslope turned to downslope, temperatures were even allowed to leap all the way into the mid 50s, which is not what anyone had in mind. The top forecast was issued by the trio of The Weather Channel, Weatherbug and Forecast.io, but everyone was within 2 points of one another. That isn’t a good thing.

It sure got cold for the holiday week, didn’t it? All that started with a cold front that arrived over the weekend, and clipped Terre Haute just after midnight on Sunday morning. After nearly a half inch of rain on before midday on Sunday, temperatures peaked in the early afternoon, and dropped precipitously, reaching the mid-30s before Sunday turned to Monday. The forecast was actually pretty solid all the way around, with the top forecast going to the National Weather Service and Forecast.io, but weren’t markedly better than everyone else.

Chilly mornings in Weirton

Ryan Henning Leave a comment

It seems like a trend of late, where we keep getting these forecasts that bust because morning lows are cooler than expected. This is what happened in Weirton as well on Thursday and Friday, with morning lows settling in about 5 degrees cooler than expected. The rain that the city saw wasn’t a hang up, and the high temperatures were pretty well in line, but those pesky lows…. Ultimately, the rain was a hang up for Weathernation, who lost out on the top spot because they didn’t have it for Friday, but Accuweather and the National Weather Service did, and were able to overtake WeatherNation to secure a victory.

Overnight drops

For as heavily as the northeast has been impacted by the weather this year, and all the talk we get every winter of nor’easters and what not, the little round of showers that passed through on early Wednesday morning is almost mythological. The 5 hundredths of an inch that came to Portland on Wednesday morning before the sun was up registered only in the observations at the airport. For the first time in November, the win didn’t go to Victoria-Weather, but rather to Weatherbug. The big differentiator was the low temperature forecasts, as the low temperatures were much cooler than expected.
