RIVER AND WEATHER CONDITIONS


Prepared for Waterways Assn. of Pittsburgh Meeting 3/11/09

National Weather Service Forecast Office, Pittsburgh PA

WEATHER RECAP


February was a rather benign weather month with below normal precipitation and near normal temperatures. The most significant weather and hydrologic event occurred from 7 – 12 February when warm temperatures melted most of the snow pack. Snowmelt and a 1.00 - 1.50 inch rainfall across northwest Pennsylvania combined to move all of the ice out of the Allegheny basin.
Overall precipitation totals for the month were below normal as was snowfall. There were only two significant rainfall events of an inch or more on 10-11 February and 27 February. Precipitation averaged 1.50 – 1.75 inches which was 0.50 – 1.00 inch below normal.
At the Pittsburgh International Airport monthly precipitation was 1.56 inches, which is 0.18 of an inch below normal. Temperature averaged 0.7 of a degree above normal. Snowfall for February was 7.1 inches which is 1.4 inches below normal.
For the first 10 days of March temperatures were 3.6 degrees/day above normal and precipitation was 0.33 of an inch which is 0.66 of an inch below normal. The seasonal snowfall total is 39.5 inches which is 5.3 inches above normal

RIVER FLOWS and ICE


From 7-12 February temperatures averaged nearly 15 degrees/day above normal which eliminated virtually all of the snow pack in the region. Ice began moving out of the upper Allegheny River near Oil City on 11 February. The ice continued to move out of the Allegheny River through 12 February. By late in the day on 12 February, moving ice stretched about 75 miles from the Montgomery Locks and Dam to near Kittanning.
Average monthly flows were near normal in the Monongahela River basin and above normal elsewhere. River rises from 8-12 February were 6 - 12 feet on the Allegheny River, 5 – 7 feet on the Monongahela River, and 6 – 15 feet on the Ohio River. A second minor rise of 2 – 4 feet occurred on 27 - 28 February on the Allegheny and, Ohio Rivers.

HIGH WATER POTENTIAL


The high water potential is below normal for the Monongahela River and near normal on the Allegheny and Ohio Rivers. Flows are 20 - 50% of normal In the Monongahela River, 200-300% of normal in the Allegheny River, and 150% of normal on the Ohio River. The recent warm period has eliminated the snow cover in the upper Ohio River Valley. A widespread 2.0 to 2.5 inches of rain and/or snowmelt in 6 to 12 hours will bring rivers to bankfull.
