Windy and cold won’t last long…

January 28th, 2012 at 9:39 pm by under Weather

Today’s peak wind gust was 43 mph at the Dayton International Airport, and other communities saw even higher gusts… with an estimated 50 mph reading up in Urbana.  The reason for this, is we have a tight pressure gradient over the area.  The pressure gradient force is the force produced when air with different pressures are placed next to each other– high and low pressure.

There is a strong Low northeast of us, and an area of high pressure to our southwest.  Air flows clockwise around high pressure and towards low pressure.  So our winds are from the west.  This will continue into Sunday… and even be enhanced by a cold front moving through the region through early Sunday afternoon:

This will kick off a few more scattered snow showers, but as has been the case lately… accumulation will be light.  A half-inch will be possible in spots–especically in the northern counties.  We are right back to dry weather for Monday, but it does look like we’ll once again see lots of clouds this week.  Along with the clouds comes warming temperatures, however.  We’ll see mid-40s on Monday, and readings near 50 for Tuesday and Wednesday!

Of course, as it warms you know we’ll see a chance of RAIN before long.  Yes, rain… not snow.  Our mild and wet year continues!  Miami Conservancy District’s dams are already storing water this year… and in fact, they set a new record last year.  Here is the info:

For the first time this year, all five Miami Conservancy District (MCD) dams are storing floodwaters that otherwise could flood cities along the Great Miami River. Piqua, Troy, Tipp City, Dayton, West Carrollton, Miamisburg, Franklin, Middletown, and Hamilton are protected from flooding by MCD’s integrated system of dams and levees.

Storage at the dams as of 2:30 p.m.

·       Germantown Dam: 34.73 feet (storage begins at 12 feet); peaked at 35 feet 1 p.m. today; dam height 100 feet

·       Englewood Dam: 24.16 feet (storage begins at 11.5 feet); still rising; dam height 110 feet

·       Lockington Dam: 16.15 feet (storage begins at 12 feet); peaked at 16.31 feet at 9 a.m. today; dam height 69 feet

·       Taylorsville Dam: 17.13 feet (storage begins at 15 feet); still rising; dam height 67 feet

·       Huffman Dam : 13.72 feet (storage begins at 11 feet); still rising; dam height 65 feet

Huffman Dam is expected to peak this evening while Taylorsville and Englewood dams are expected to peak on Saturday and Sunday, respectively.

In 2011, concurrent storage of the five dams occurred on seven different occasions – a new record for MCD. Previously, the largest number of annual high-water events resulting in concurrent storage at all five dams was four.

The MCD flood protection system is designed to protect to the 1913 levels plus 40 percent. During the Great Flood of 1913, the region received between 9 and 11 inches of rain between March 23 and 25.

Have a good Sunday!
