March melt down

Last week was a warm one. It stood out in a summer of record heat across the world, and particularly in the Great Lakes region. Fond du Lac, our forecast city on Monday night, saw temperatures launch all the way into the low 70s on Tuesday, which even exceeded the expectations of our forecast outlets. Naturally, warmer forecasts had better scores, but curiously, the clouds were clear enough to allow for chilly overnight lows. As has often been the case this year, it was The Weather Channel who collected the top forecast.

One last chill before spring

It sure seemed like the cold air that trailed last weekend’s winter storm is a last gasp of the winter, given how warm it is going to be this week. Peoria even had the dignity to be colder than forecasts originally indicated by a handful of degrees. One outlet pegged the high temperature forecast on both days, thanks to a cooler numbers than most of the other outlets (except Weatherbug, of course). That top forecaster was The Weather Channel.

Should have trusted my gut

I noted in my forecast that I admired the outlets that were leaving rain out of the forecast in Huntsville for Monday. I thought what was showing up in the model guidance was just an overzealous interpretation of the increasing clouds in the area ahead of a cold front and vorticity maximum along the Gulf Coast. I also (this time correctly) suspected that this vort max would reduce overall rainfall in Huntsville, drawing it all into the center of circulation. I should have trusted myself on both accounts, because it didn’t rain a drop on Monday. Not that getting it correct would have helped. Clime ended up winning this one.

In like a Lion

Birmingham was getting ready for a line of thunderstorms as we put our forecast together last Wednesday. After the line went through, temperatures were cooler and it was dry to end February. Things took a turn on Friday, when the next round of wet weather moved into town. This round brought about .8″ of rain, a not insignificant amount, and certainly a bad sign for the weekend. If one believes in omens, this must also mean that the month of March will be out like a lamb in Birmingham, so that’s a good sign, right? Victoria-Weather easily won the forecast.

Soggy conditions for NorCal

Our forecast for Merced anticipated yet another round of wet weather coming into the West Coast. Unlike previous iterations of the relentless storms pounding the Pacific Coast this year, the emphasis of this storm was on the Sierra Nevada, where blizzard conditions shut down the region. Still, it was a healthy storm for Merced, where nearly an inch of rain fell in town on Friday. Despite all the headwinds against us as a community of forecast outlets (A large system moving into the west coast, with undulating terrain leading to unique microclimates), the numbers ended up pretty good for everyone, including a three way tie atop the leaderboard, from The Weather Channel, Weather Service and Weatherbug.

A little of both

There was a little bit of a debate for the forecast for Ocean City. Would the system moving through be quick and usher in colder air? Would it be slow and let some light rain linger into the weekend? Most outlets kind of hedged. The clouds would linger, and the cold air wouldn’t arrive. Instead, there was light precipitation early Saturday morning AND the cold air came in. Victoria-Weather went the cold route along with Weatherbug, while Accuweather was the only outlet that had rain on Saturday’s forecast, and everything worked out to a three way tie, with all others several points off. I should note, this is the one rare site where I do not use an NWS observation point, because the nearest is Atlantic City, another site we might forecast for, so I used the nearest site available from Weatherforyou.com.

A beautiful bounce back

It’s good to be in San Diego. Just a statement for always, but also specifically now, where last week, weather bounced back pretty nicely after significant rain caused problems for most of Southern California early last week. It continued a trend of flooding rain across the region to start 2024. It wasn’t quite the issue to end last week. After a chilly beginning on Thursday, temperatures started climbing and the sun came out, preventing even wispy morning fog. The Weather Channel turned out the top forecast, narrowly edging their oppoinents.

Dropping Off

Things sure can change in a week. We looked at Springfield, Massachusetts about this time last week, and it was ensconced in high pressure. This led to a pretty quiet forecast with a broad range of temperatures. Today, weather has rolled in, and many parts of New England and the Mid-Atlantic are seeing significant snowfall, and in some placed, seeing it for the first time in a while. The biggest hang up in the forecast was that dynamic change in temperatures, especially at night. Clouds never really played a factor, and the morning low on both Wednesday and Thursday fell below expectations. Clime had a good day, however, and was rewarded with the top forecast for the day.

The atmospheric stream

The “atmospheric river’ terminology is one that has really captured the imagination of the media, and we are hearing it quite a bit right now as rainfall is inundating southern California. The atmospheric river is simply a strong active jet stream, and when it comes from the sea, there is more moisture available, and “more moisture” isn’t something we think of when talking about southern California. In fact, last month when we were forecasting for San Luis Obispo, I thought the few showers showing up in the area were remarkable enough to call them out ostentatiously. The rain seen now in the LA Basin is several orders of magnitude larger than that, so if this is the atmospheric river, then what we saw in late January was a mere stream. A trickle. For the day, WeatherNation had the forecast victory, being the best temperature forecaster among outlets that left rain in the forecast on the 25th.

Uncharacteristically chilly

I know there is a “North” in the name, but you don’t usually think of sub-freezing temperatures in Charlotte, North Carolina. That’s exactly what they saw on January 19th and 20th, though. Most of the 20th, in fact, was below freezing, with highs remaining in the mid-30s. It’s been an active month, and post frontal cooldowns are becoming many in the southeast are getting used to enduring. The Weather Channel and Accuweather tied for the top forecast, missing out, as everyone did, on the end of the rain associated with that cold front sweeping through. No rain on the 19th.
