Weekly Review Oct. 28 – Nov. 3, 2019

stnplot_2019102810/28 – As mentioned in the previous post, the cold front began to form waves of low pressure along it. As they moved from south to north, they would bring more moisture. In this case, more light rain and drizzle. Temperatures remain warm enough that no snow fell during the day.

One thing to note. I’ve been using the Gaylord, Michigan Co-op observation which covers the 24 hour period of 10/28 7am (the time of the map) to 10/29 7am (EST). So the observations read one day ahead, but the observation covers the daytime and night of the 28th, into the morning of the 29th.

Observation:
High: 48° Low: 31° Precipitation: 0.22″ Snow: 0.0″

stnplot_2019102910/29 – We begin the march of the Alberta Clippers, which seems to really usher our winter. Of course, they aren’t the only lows we get, but they are the main low pressure systems that seem to affect us. So the clipper on the map, that is moving from NW Ontario, into Lake Superior helps to push the stalled front that has been over us for a couple of days east by the evening. High pressure then built into the region and cooled things off.
Gaylord Co-op Observation:
High: 39° Low: 30°
Precipitation: 0.02″ Snow: 0.0″

stnplot_20191030

10/30 – For the beginning of the day, high pressure was in the region, but was being pushed back out from the low pressure in the Southern Plains. Again, waves of low pressure moved up the front, as the low near Texarkana moved to the NNE toward the Lower Great Lakes, and with another forming behind it. This put us into the coldest part of the storm, but we didn’t get cold enough for snow until late Wednesday night and early Thursday morning (10/31) and then we only got a few tenths of an inch.
Gaylord Co-op Observation:
High: 42° Low: 30°
Precipitation: 0.25″ Snow: 0.4″ Snow depth: T

stnplot_2019103110/31 – So the snow that we got by the morning remained as we stayed in the cold side of the low pressure as it moved up into Lake Erie, and on into New England. This brought snow across northern Michigan, mainly in northern lower Michigan. While the snow map on the morning of the 1st is snow depth, it was pretty much the snow we got from the night of the 10/31.
Gaylord Co-op Observations:
High: 32° Low: 29°
Precipitation: 0.15″ Snow: 1.0″ Snow depth: 1″2019-11-02 00_32_06-Window

stnplot_2019110111/1 – As the system from the day before left, the high pressure built into the region and lake effect snow continued, in some areas. Snow, overnight, wasn’t as big of of a deal as the warmer air during the day began to melt the 3-5″ from the night before, so that there were bare patches around the region, and roads were just wet.
Gaylord Co-op Observation:
High: 35° Low: 29°
Precipitation 0.12″ Snow: 1.0″ Snow Depth: 1″

stnplot_2019110211/2 – The rain/snow mix in the morning began to quickly diminish as the colder air began to move into the region. By the afternoon, a lot of the snow on the ground had disappeared. However, the air mass began to get colder, and the fetch over the Great Lakes began to lengthen. This lead to some decent lake effect bands that produced some significant amounts in the area, that in the office we call, “the big three” (Antrim/Otsego/Charlevoix, see the link to see why). It looks like the WNW flow, however, didn’t produce much in the way of snow in Sault Ste. Marie and that portion of Chippewa County, usually another big snow region.
Gaylord Co-op Observation:
High: 36° Low: 28° Precipitation: 0.36″ Snow: 6.2″ Snow depth: 6″

stnplot_2019110311/3 -The winds began to veer through the morning from west to northwest, and we headed into our first real lake effects snow  period. We did have some locations mix with rain, but overall, we got snow bands in eastern upper and northwest lower Michigan.
Gaylord Co-op Observation:
High: 34° Low: 26°
Precipitation: 0.13″ Snow: T Snow depth: 2″

Weekly Review Oct. 21-27, 2019

stnplot_20191021
10/21 – The low pressure in the Mid-Mississippi Valley spun in place for a while, slowly moving into Lake Superior by the late evening. This kicked off periods of rain over northern Michigan. Temperatures continued to be a bit above normal. The winds with the system, however, were the strongest on the front end with the highest wind gusts being reported on 10/21.

Gaylord Co-op observations:
High: 54°
Low: 43°
Precipitation: 0.43″
Snow: 0.0″

stnplot_2019102210/22 – During the morning, the dry slot moved over the region and even cleared the sky out for a time. At 530 am, when I arrived home from my night shift, I could see the stars overhead. However, the winds were already picking up again.

The storm remained around the western part of Lake Superior, the winds picked up out of the south and west beginning an assault on the Lake Michigan shores of northern Michigan. There were numerous reports of lakeshore flooding and beach erosion.
Gaylord Co-op observations:
High: 47° Low: 38°
Precipitation: 0.03″ Snow: 0.0″

stnplot_2019102310/23 – The winds continued to gust to gale force on Lake Michigan in the morning. By the end of the day, the winds had diminished. However, the rain didn’t stop as lake effect rain showers continued into the afternoon. And just when you thought the rain was done, a wave moved up the front, and produced more rain over the region. Although, most didn’t fall in Gaylord.

Gaylord Co-Op observation:
High: 43° Low: 37°
Precipitation: 0.07″ Snow: 0.0″

stnplot_2019102410/24 – After the cold front went through the state, high pressure built in the state and the weather dried out. Temperatures warmed up a bit.
Gaylord Co-op observations:
High: 45° Low: 30°
Precipitation: 0.01″ Snow: 0.0″

stnplot_20191025 10/25 – The High pressure remained for another day, but things began to cloud up, as the next system started to move out of the Gulf Coast and north into Southern Plains. Not as warm, because of the clouds.

Gaylord Co-op observations:
High: 42° Low: 23°
Precipitation: Trace Snow: 0.0


10/26 – “Olga, ” which was probably at least a depression on the morning of the 25th, deepened and moved ashore. By the morning of the 26th was in the Lower Mississippi Valley and forecast to move north into the Upper Great Lakes. So the day started dry, on the 26th, only for things to cloud up and the rain to begin to move into northern Michigan late at night.

Gaylord Co-op observations:
High: 49° Low: 24°
Precipitation: 0.98″ Snow: 0.0″

stnplot_2019102710/27 – By the morning of the 27th, the now extratropical low was occluding and beginning to move on. High pressure built into the region and the cold front to the west began to form waves on it, as an area of low pressure at 500 mb(~18,000ft) was developing  over the Rockies. As the upper low moved out, the cold front began to slowly move to the east and into Michigan. The precipitation was mainly light rain from the morning of the 27th.
Gaylord Co-op observation:
High: 48° Low: 32°
Precipitation: 0.02″ Snow: 0.0″

 

Weekly Review Oct. 14-20, 2019

10/14 – The cold front moved through and high pressure began to build into the region. However, with the colder air, we had some lake effect rain and snow.
Gaylord Co-op
High: 37° Low: 33°
Precipitation: 0.31″
Snow: T

Here’s the 24 hour radar, rainfall analysis:

10/15 – The low pressure moved up into the Upper Mississippi Valley by the next morning and then began to move into the Upper Great Lakes, and northern Michigan. This brought rain back, but not before a little snow mixed in initially in the morning. Gaylord Co-op: High: 44° Low: 29° Precipitation: 0.27″ Snow: T

10/16 – Temperatures went up initially as the the warm air moved into the region on the night of the 15th, then with the low over northern Michigan, the temperatures didn’t go anywhere as the low temperatures remained in the middle 30s, and the highs remained in the lower 40s. So lake effect rain continued into the morning of the 17th.

Gaylord Co-op:
High: 43° Low: 37°
Precipitation: 0.29″
Snow: 0.0″

stnplot_20191017 10/17 – The drier air finally won out by late in the day. The rain was light as is most lake effect rains. Eventually, there were some breaks in the clouds late, and the sky cleared overnight. 

Gaylord Co-op:
High: 45° Low: 30°
Precipitation: 0.02″
Snow: 0.0″

stnplot_20191018

Gaylord Co-op:
High: 51° Low: 32°
Precipitation: 0.00″
Snow: 0.0″

 

stnplot_2019101910/19 – As the high retreated to the east, the warm air continued to move into the region, and brought us to above normal temperatures, approaching 60°. However, the cold front moved into the region, and brought a little rain to northern Michigan. 

Gaylord Co-op:
High: 57° Low: 38°
Precipitation: 0.02″
Snow: 0.0″

stnplot_2019102010/20 – The cold front moves through northern Michigan in the morning, The front was rather dry, as little rain fall with it. When it  went through. High pressure then quickly built in and the sky cleared out. Temperatures again were above normal.

Weekly Review for Sept. 30-Oct. 6, 2019

Something new I’m trying to do on my blog, so I can keep it going. I’m going to try and do a weekly weather review for northern Michigan. So, let’s take a look at what occurred at Gaylord (the automated weather system at the airport) over the last week from the Local Climatological Data. In the future, I’ll add the co-op site as that’s where the snow amounts come from.

So on September 30th, an area of low pressure moved from the Northern Plains and into the Upper Great Lakes.

Daily 7:00 AM E.S.T. Surface Map and Station Weather

We didn’t get much, as the rain really didn’t kick off until after midnight on the 1st. This was the last of the truly warm weather, as the cold front that eventually moved through the region cooled us off by 20 degrees.

Light rain then continued for the next 4 or 5 days, and temperatures struggled to get to 60 degrees over most of northern Michigan.

A New Something Possible….

What am I talking about? Well, in recent days I’ve been contemplating a blog/vlog/podcast that is weather oriented. It will describe more about the basics of weather, although, I’m still hashing this out. Hang in there. More information forthcoming as this develops.
