Cyclogenesis Bomb

posted in: Winter Storm Warning | 94

Cyclogenesis is the rapid development or strengthening of a low pressure center.  A cyclogenesis bomb is where the central barometric pressure drops at least 24 millibars in 24 hours.

This is the latest from the NWS in regards to the high winds today:

Strong and damaging winds are almost certain today with gusts in the middle of the night across portions of MO and IL to in excess of 60 mph, and the low will only continue to deepen today as it works northeast through the area. A concern is the fact that this low will move on a track closer to our area than the 1998 Fall Storm, the Fitzgerald Storm of 1975 or the Armistice Day storm of 1940. All of those systems tracked further west across Wisconsin. This storm will move across Lake Michigan today which will put the rise/fall pressure couplet and therefore the strongest winds right through our area. Model cross sections in BUFKIT continue to show mixing depths tapping 65 knots around 4,000ft. Winds in excess of 50 mph are a certainty, with 60 mph likely and even higher values possible.

Below is the HRRR model for wind gusts today at 10 meters (33 feet):


This is the point forecast for wind gusts (Allegan County):  The blue line is the gusts, the line below is wind speed and direction.


This is a good time to make sure all your mobile devices are charged – the winds are starting to pick up and we will start seeing some snow shortly.  I live in a valley but can see the tops of the trees swaying.

You can keep track of current conditions on the front page here – I have a ticker on top with the current warnings for the area.  Stay safe……

What a storm! Wind, cold, snow, near blizzard conditions, horrendous roads, school closings and power outages, but don’t worry, some on here said no big deal!

So all the crews that were here by our house have left. I’m guessing they’re waiting till daylight to replace poles? There are a couple with the tops of the poles still connected to the lines just blowing around in the wind. I’ll try and get some pictures soon if I can get the spot light on hem to light them up.

It’ll be so nice when the warmer weather arrives and you can actually go outside and enjoy the warm temps and the world comes back to life after the death of winter!! So awful being cooped up in the house all day with these terrible winds and cold temps! Looks like another awful Monday and then weekend coming up!! With temps far too cold to go out and do anything outside. The warmer temps are coming, just hold on, the winter misery will be over soon!

The snow just keeps coming up here in northern Kent county! It has been snowing all afternoon and evening up here! The roads are horrendous and the school closings are starting to come in! Still very windy and low visibility! Wow what a storm!

So even bigger trees came down by us now on the power lines. Biggest blue explosions I’ve ever seen! Snapped several telephone poles like twigs, lines down everywhere, what a mess! All generators are now fired up and running.

Another swing and a miss for the RDB today with less than an inch of snow here!! Also not sure what snow maps to believe that he is posting?? The first 5 day snow map he posted earlier this morning showed 14 inches of snow for my area, then the next one he posted a few hours later showed around 8 inches for my area, now this most recent one showed 4 to 6 inches for my area!!! LOLLOLOL!! Those maps are hilarious!!

Two things looked great today.

1. The MSU basketball team that took it to u of m on their home court. (Sorry u of m fans but you get another chance in a week or so).

2.The RDB model that predicted 2 to 4 inches of snow and near blizzard conditions! For GR! Another bingo! Incredible!

I figured without Langford and Ward (30 ppg), Blue would have won by 15 or more. State’s defense was outstanding in the 2nd half. Only three bench players, though. The starters can’t keep playing that many minutes.

Rocky (Rockford)

Very good points and the fact MSU overcame 2 of their leading scorers not playing was impressive!

Zero snow falling here, visibility is normal. Here’s a pic of our back yard. Very little snow, you can see the grass poking through. Most of what you can see is ice from all the water in the yard that froze:

Don’t worrry Indy the warm weather fanatics said this storm was no big deal and questioned why were in a watch! No big deal, just near blizzard conditions, snow, poor visibilities, 40 to 50 mph winds and very slippery and icy roads! Kent should be in a winter storm warning as we speak!! Incredible storm!

Not here. I heard there was suppose to be and I think on the radar it showed but I honestly am not positive. Maybe you can back up a radar and look at that time.

Snow has pretty much stopped here now. I would guess about an inch, but of course it has all blown far away and not accumulated anywhere. Good call going with the high wind warning as this is definitely NOT a blizzard.

Sandy (Hudsonville)

I see that. I was just debating on weather to fire up the generators or not. Guess I’ll wait a little bit yet. At least we have the most critical utility…..WI-FI! Ha!

Highest wind gust here was 45 just before our power went out at 11:30. Of course now with no power I have no way of checking my pws. Guessing by visually looking outside I would say we have for sure topped 50mph several times. Lots of trees snapping all around the area here.

Looking ahead we have a nice little snow storm coming Tuesday and next Saturday even bigger storm showing up on the models that would give all of Michigan probably a Blizzard that is a ways out but models been pretty darn good this winter something to think about….The winter that keeps going INDY..

The peak gust at my house so far today is 39 mph. That’s windy enough for me! I don’t want to know what 50-60 mph will sound like!

No snow. Getting sporadic peeks of sunshine. Just retrieved our trampoline from a couple of houses down. Too windy to pull it back so I used the lawn tractor and a tow strap. Put it near the house and weighted it down with some bags of top soil and salt. Tis breezy!

Not quite a “blizzard” here but getting moderate snow fall and blowing snow at this time with a temperature of 31
Here is the NWS definition of a Blizzard

lizzard
(abbrev. BLZD)- A blizzard means that the following conditions are expected to prevail for a period of 3 hours or longer:
Sustained wind or frequent gusts to 35 miles an hour or greater; and
Considerable falling and/or blowing snow (i.e., reducing visibility frequently to less than ¼ mile)

Well it appears the storm has moved in. Very windy here now and snow is flying. The wind is howling thru here. I wonder what the speed is??

What is the windspeed by you?

Slim

The official high for Grand Rapids for today will be 46 here at my house it was 41.6 the current temperature here at my house is 33.5 and at the airport the last reading was 35. At this time I am getting of and off light snow showers. It is windy but as of yet not too bad. The lowest pressure at GRR was 987.1 and the latest was 991.3

It looks like the low is close to the Sault as there last reading there was 979.8 and falling.

What are you talking about and where have you been! I post snow maps for your viewing pleasure.

Alright, let’s revisit this Thursday! Rocky and his “RDB Model” is saying this model is accurate and a “bullseye”, so let’s all look at this Thursday and see if we get the 14 inches of snow that this is calling for in Northern Kent County, heck I’ll even give it til Friday since it’s a 5 day map! But 14 inches is his call for accumulated snow from now til Friday!

The forecast discussion is the only thing updated on the NWS GR website. They need to get it together. The warnings on the main page have not been updated. Even if you click on the Watches, Warnings, and Advisories link on the main page, you only see the ones from yesterday. Did the govt shut down again??

Fortunately, we have Michael’s ticket above 😬
