Breaking out in Wyoming

The Easter weekend was downright wonderful in Wyoming’s capital and largest city. The sun was well anticipated by forecasters everywhere, but it was even stronger in Cheyenne than most people expected. On Saturday and Sunday, the high was 66, boosted by clearer skies than anticipated, and winds that were more quickly from the west, contributing to downsloping flow and a quick warm up. There was a tie at the top, as Accuweather and The Weather Channel drew level.
Actuals: Saturday – High 66, Low 39

Cheyenne, Wyoming

Hello, happy weekend. I hope you find yourself among friends and family this weekend, and the weather is hospitable.

At 553PM, MT, Cheyenne was reporting a temperature of 61 degrees with clear skies. Cheyenne found itself in a bit of a cold pool, as the rest of the High Plains, from Nebraska south to eastern Colorado were well into the 70s.  This was due to a thunderstorm that had erupted about 15 miles to the northeast of Cheyenne, with cold downdrafts bringing Cheyenne’s temperatures down by 7 degrees just as the day’s temperatures were scheduled to peak.
There is a broad upper level trough moving into the northern High Plains, but if there is any surface development, it will be in western Ontario and the Upper Midwest. After some cooler air sinks south towards Cheyenne, expect a fairly tranquil weekend, albeit chillier than how the work week ended. A west wind on Sunday should bring those temperatures back up, ever so slightly.

I guess Forecast.io isn’t buying the cooldown. Wow. Here is the radar, showing the cell popping up just northeast of Cheyenne.

The undercard

 The big story out of a massive cut off low parked over the central Rockies has actually had more to do with the awful flooding in Houston and severe thunderstorms across the rest of the state. Underneath the trough, things were still quite active, but reflected a different season entirely. There was rain at lower levels, but a lot of late season snow in the mountains. In Cheyenne, they stayed clear of most of the precipitation for the past pair of days, but there was a little bit of light rain reported yesterday. The clouds and overcast and pool of Canadian air did mean that temperatures were well off the pace of areas around them. Forecast.io was the owner of the top forecast, with highs sneaking up towards the warm end of forecasts.

Cheyenne, Wyoming

After so much talk about warm ups and how nice things are getting across the country, let’s just say we are in for a rude awakening as we begin our forecast in Cheyenne.

At 953PM, MT, Cheyenne was reporting overcast skies with a brisk north wind and a temperature of 30 degrees. There was snow being reported in Laramie and other places in higher terrain west of town, with a little bit of light rain reported in Kimball, just over the border in Nebraska.  The low tops to the clouds meant that the activity was barely visible on radar, though it has been widely encapsulated into the latest model guidance.
A cut off upper level circulation is barely reflected at the surface, but it continues to churn, centered along the Wyoming/Colorado border.  Eventually, there is a a trough moving through Canada — northern Canada at that — that may try to absorb the system well to the south  and begin the rocess of a warm up, and dry out in Cheyenne, however this is not anticipated to happen until after our forecast period expires. For our purposes, anticipate continued overcast with periodic bouts of precipitation. Some afternoon rain might mix with snow overnight.

Nobody is on the same page for tis forecast. I think the chances are better for precipitaton than not, but again, I think the best chances come with even higher elevation. Let’s see what happens. Radar is not terribly impressive. The real show is in he satellite, because it’s low clouds preducing any precipitation.

Cheyenne

Perfect, delightful storm

Everything came together perfectly for Cheyenne over the last couple of days. Sunshine, high pressure, downslope flow, and guess what? Cheyenne was fantastic on Monday. Temperatures jumped from 50 degrees to the mid 60s on Monday, thanks to all those factors. This is even more impressive when you consider it was 6 degrees on Sunday morning. The most effective forecaster for this crazy fluctuation was The Weather Channel, who seem to handle the dichotomy pretty well.

Cheyenne, Wyoming

This was supposed to come last night, but did you SEE that Northern Iowa shot? Holy buckets.

At 853AM, MT, Cheyenne was reporting a temperature of 21 degrees with clear skies. A deep spring trough was perched over the northern Plains, and is bringing unseasonably cool air into the region, with snow falling across the Plains as far south as western Kansas. Things look to be improving for Cheyenne, with a sharp ridge over the Rockies moving into the high Plains.
A weak bowling ball of vorticity is going to sink from Minnesota into the Mid-Mississippi Valley and will allow the environment in southern Wyoming to further wind down. The calm weather will allow for a significant warm up, thanks in part to the sunshine and in part to an increasingly southerly flow. Expect a tranquil day, particularly for the High Plains which never seem to be quite this serene.

Pretty fantastic weather for late March in Wyoming. No complaints here!

Gulfport, Mississippi to Cheyenne, Wyoming

We’re off on a three day excursion that, for the most part, will take us through the Plains and into one of the most active parts of the country lately. It’s 1492 miles of discovery between the two towns, and we will cover them at a pace of 64.4mph. The first two days of the trip will be a little bit longer, and we willattempt to cover 515 miles on those two days. Away we go!

DAY ONE (Saturday)
Gulfport
Thunderstorms along the Gulf Coast will take a while to get going tomorrow, which is good news, as we will see pretty tranquil conditions through southern Mississippi and Louisiana as we take I-10 to Lafayette before turning north. Our cross-wise drive through Louisiana may be increasingly cloudy, but by the time we hit Shreveport, the sun will be back out. WE will very nearly make it to Oklahoma, but will stop just to the southeast of Paris, Texas, in the tiny town of Pattonville.

DAY TWO (Sunday)
Much of the day will be pleasant in the southern Plains. Well, pleasant to drive in, especially if your air conditioning works. A system working through the northern Plains is expected to dangle an unusual early summer cold front through the central Plains, and will begin to stall right along the final stretch of our drive. Some big time thunderstorms will be posible north of McPherson, Kansas and could continue the rest of the way to the desolate little town of Bunker Hill. The thing about these storms is that they will be at the tail of the system, and will likely thrive on strong updafts. Don’t be surprised if we end up with some dents in the car, thanks to large hail.

DAY THREE (Monday)
It’s possible that it storms all night in Bunker Hill, but it will be clearing out as we head out on Monday morning. Expect a little bit of morning haze across the prairie, but clearing skies and some sun peeking out behind us (as it rises in the east, after all). We will likely see some thunderheads in the horizon, as a northwesterly wind will contribute to some upsloping thunderstorm development in the Rockies. By the time we reach those same mountains, the activity will be much less significant. There could still be a stray shower, but likely no monstrous super cells to finish off the drive from Denver to Cheyenne.

Wet snow rides the chinook

I say in the title there was a Chinook, but Cheyenne didn’t really feel the very warm temperatures that are often associated with brisk west winds. And they were brisk, reaching 35mph on Sunday. Saturday was a drier day, but Sunday brought some mixed precipitation in the evening. The brisk northwest wind coming over the northern Rockies was able to bring enough moisture over the mountains to provide an inch of snow at the airport and a little bit of rain. Victoria-Weather was the only sucker to believe in the power of mechanical heating, but the National Weather Service was able to hit the temperature and precipitation forecast better than anyone.

Cheyenne, Wyoming

We’re cruising into Christmas week, and we will definitely get there. First, we have a stopover in Cheyenne.

At 353PM, MT, Cheyenne was reporting a temperature of 35 degrees with clear skies. Continued troughing in the northern Plains has led to brisk winds spilling over the Laramie Range, and high wind watches are out for the mountains. Cheyenne seems to be in a shielded location, as they are presently reporting calm winds. Still, breeze west winds suggest a warm night, particularly since it seems unlikely that the wind will stay calm forever.
A vast and strong jet moving into the northern Rockies will also bring along a great deal of moisture into the region. While most of the shower activity will be confined to the more mountainous regions, by Sunday afternoon, it’s certainly a possibility that Cheyenne will see some scattered rainfall. The biggest issue with this system will be very gusty winds as the jet noses into the northern High Plains.
Tomorrow – Mostly cloudy, High 49, Low 28
Sunday – Increasing clouds, with some light rain possible late, snow in the mountains, and very windy, with gusts to 40mph possible High 54, low 30.

TWC: Tomorrow – Partly cloudy/wind: High 43, Low 29
Sunday – Mostly cloudy/wind: High 46, Low 29

AW: Tomorrow – Intervals of clouds and sunshine High 45, Low 28
Sunday – Mostly cloudy and increasingly windy High 48, Low 27

NWS: Tomorrow – Mostly sunny High 46, Low 24
Sunday – Partly sunny (rain mixing with snow after 5pm) High 49, Low 25

WB: Tomorrow – Partly cloudy. High 45, Low 22
Sunday – Mostly cloudy. Windy High 50, Low 25

WN: Tomorrow – Partly Cloudy High 46, Low 23
Sunday – Windy with Isolated Snow Showers High 50, Low 25

Models are currently proving unable to match the warmth produced by the chinook winds in Cheyenne, and I believe in their ability to heat things up, even if it’s briefly, this weekend. I believe in the power of mechanical warming! Anywho, here’s the satellite, showing off some clouds in the center of the state.

Saturday: Trace of rain in a shower. High 53, Low 36.
Sunday: 0.02″ of liquid precip, 0.1″ of snowfall. High 43, Low 31.
