HAPPY HALLOWEEN

It was another cold start this morning with temperatures in the 20s. Thursday morning might be a few degrees warmer with a few clouds moving into the area later tonight. Here are the morning lows.

I hope you have a safe and fun evening out. The weather looks great this evening. Here is your Trick or Treat forecast or as I titled it ScareCast.
Don’t do what I did when I first went trick or treating as a kid. I went to the door and the person gave me some candy. I would than sit on the stairs and eat it. Go to the next house and get candy…sit on the step and eat it. After the third time of this my Mom had to stop me and tell me that I couldn’t just eat my way from house to house. I wonder what my daughter will do next year. This year she is too young to be eating most of the candy. Anyway, the weather this evening will be nice. 

While you are out this evening…check out the Moon it will be pretty bright. The Full Moon was on Monday. While looking at the Moon, look to the bottom left of it and you will see the planet Jupiter. You will be looking east.

The dry weather will continue through Friday. Clouds will be increasing Friday afternoon as a surface low and upper level low move across the Midwest with clouds and a slight chance of light showers Saturday and Sunday. Here is the upper level low on Sunday morning.
Next week will remain slightly cooler than normal. A front is forecast to cross the state on Tuesday with a slight chance of showers. Other than the front on Tuesday, more dry conditions and below normal temperatures are expected.

October 31

From NWS
1991
: A major winter storm pounded the upper Midwest from October 30th into November 2nd with some of the most severe effects occurring on Halloween. Snow moved into southern Iowa on the afternoon of the 30th and changed to mixed precipitation and ice on the morning of the 31st and continuing into late afternoon on November 1st. Total ice accumulations ranged from 1 to 2 inches from southwestern into north central Iowa and 2 to 3 inches across southern and southeastern Minnesota. In northwestern Iowa the precipitation fell as all snow, with total accumulations of 8 inches or more across the area ranging up to 15.0 inches at Estherville and strong winds producing blizzard conditions into November 2nd. The damage and hazardous travel conditions were so severe and extensive that 52 of the 99 counties in Iowa were declared disaster areas. Highways and interstates were closed across most of the state and Halloween festivities were cancelled at many locations. As the storm system moved further northeast it dumped 36.9 inches of snow at Duluth which is the largest storm total snowfall accumulation on record in Minnesota.

This Day in National/World Weather History …
 31 October 1991 → A severe winter storm dubbed the Great Halloween Mega Stormstruck the upper Midwest. Minnesota bore the brunt of the storm. Blizzard conditions occurred with wind gusts frequently to 50 mph. By the time the storm finally ended on November 2, Duluth received 37 inches of snow, Minneapolis 28 inches, and International Falls 18 inches. For Duluth and Minneapolis, this set new all time records for single storm totals. These two cities received nearly half their normal seasonal snows in this one storm.
 31 October 1994 → American Eagle Flight 4184 was completing its last turn in holding before being cleared for landing at O’Hare Airport in Chicago. After holding in pattern for an hour in wintry precipitation, enough ice accumulated on the aircraft that the plane became uncontrollable and crashed in Roselawn, IN. All 68 on board the ATR-72-212 aircraft were killed.

Wednesday: Mostly sunny. High: 50-55. Wind: NW 10-15 mph.

Wednesday Night: Mostly clear. Low: 29-33. Wind: NW 5 mph.

Monday: Partly cloudy. High: upper 40s.

Tuesday: Partly cloudy with a 20% chance of showers.

More quiet weather across Iowa as the storm in the northeast inches its way westward. The most impact from the storm that we have and will see is the gusty wind from the north today.

The wind will diminish this evening. The storm will begin to move northeast and weaken on Wednesday. Here is the surface map from this afternoon.


High pressure will keep us dry through the rest of the week. The storm in the northeast part of the nation will be out of the country by the end of the week. At that time an area of low pressure will develop in Kansas Friday night and track east through Missouri Saturday. The map below is the GFS model for Saturday at 1 pm.

Expect clouds and showers Saturday and Sunday with a better chance of showers to be Saturday. The temperatures will be cooler due to the cloud cover for the weekend.

Monday will be dry but on Tuesday a cold front will cross the state with another chance of a few showers.

The 8-14 day outlook from the Climate Prediction Center shows temperatures near normal and precipitation above normal.

1925: Unseasonably bitter cold weather set in after a pair of early winter storms as the temperature plummeted all the way down to -15 F at Inwood setting the all-time Iowa October record. Other low temperatures included -10 F at Milford, -4 F at Decorah and Mason City, -2 F at Boone and Fort Dodge, -1 F at Iowa Falls, and 0 F at Cedar Rapids.

Sandy Comparison

Hurricane Sandy is going to lose it’s tropical features as it travels farther north. As it does the storm would be considered extatropical. The storm is going to be a historic one when it comes to how large it is, lowest pressure, snow amount (in West Virginia). The storm will bring rain amounts up to 10″ (see map below) with wind speeds near 80 mph.

There are a bunch of numbers thrown out on TV and on the web when it comes to the pressure and the wind. Some of you don’t have anything to compare it to here in the Midwest. Well here is something you can compare Sandy to. There was record setting storm on October 26-27, 2010 in the Midwest. There was a massive wind storm producing blizzard conditions, strong winds and severe weather. The lowest pressure in this storm was 955.2 mb. The pressure of Sandy at 11 am advisory, from the National Hurricane Center, was 951 mb. The lower the pressure the stronger the storm is.

Here is what Hurricane Sandy looks like on the satellite midday Sunday.

Click here to see the loop of the above image. It is a detailed loop so it takes a little longer to load but it is worth the wait.

Here is another comparison for you. How about the “The Storm of the Century” in 1993. The lowest pressure of this storm was 960 mb.

The map below shows the wind forecast for Monday evening as Sandy’s center of circulation reaches the coast. The strong winds extend as far east as Chicago. Here in Iowa our wind will NOT be strong at all.

October 28

Two-day accumulations on the 27th-28th included 2.0 inches at Corning and Keosauqua, 3.0 inches at Mount Ayr, 3.4 inches at Keokuk, and 6.0 inches at Clarinda. Unseasonably cold temperatures also settled across the state over the last several days of the month. Des Moines easily recorded its three coldest October temperatures ever in three consecutive days from the 28th-30th, the low of 7 F on the 28th still standing as the station October record today. The month would finish as the coldest October on record at Des Moines with an average temperature of only 41.6 F. Several stations in Iowa fell to or below zero on the 28th including readings of 0 F at Rock Rapids and Rockwell City, -1 F at Onawa, and -2 F at Logan and Webster City. The all-time Iowa October low temperature record would be reached at Inwood on the 29th.

 This Day in National/World Weather History …
