Heavy Rain (February 12-13, 2007) |
 |
| |
 |
During much of the first half of February, surge after surge of dry and
cold air arrived from Canada...with systems driven into Arkansas by the
Polar Jet (northwest wind flow aloft). The Subtropical Jet (southwest
wind flow aloft) took a break, with mild Pacific air and abundant
moisture avoiding the region. However, that briefly changed on the
12th/13th. |

Jet. |
| On the afternoon of the 12th, temperatures climbed into
the 50s and 60s in most areas...with readings holding in the 40s and 50s
during the predawn hours of the 13th. Moisture levels increased, with
heavy rain in the forecast. |

| Northern and western Arkansas got the brunt of the
moisture. Rainfall amounts in these areas were
generally between one and two inches...with locally up to three inches.
Twenty four hour amounts as of 6 am CST on the 13th included 2.17 inches
at Fort Smith (Sebastian County), 1.91 inches at Harrison (Boone
County), 1.88 inches at Russellville (Pope County) and 1.83 inches at
Mountain Home (Baxter County).
|
| While rain fell, frigid conditions were set to visit from
the northwest yet again. Heavy snow developed from central Missouri into
the Ohio Valley and on into New England. By the time temperatures
dropped in Arkansas, moisture had departed. Even so, there were a few
leftover flurries on the 14th/15th. |

pattern at 6 am CST on 02/13/2007...with a cold front separating
mild air to the south/east from much colder air to the
north/west. In between the two airmasses, heavy rain occurred
over northern and western Arkansas. |
