Late yesterday afternoon I went fishing at Lake Hefner, in Oklahoma City. I didn’t stay too long, as there was a fairly cold north wind and I started to get hungry. Next time I’ll remember to eat before I go, or bring food in case I don’t catch anything. 🙂
This brought to mind an article by The Weather Channel, titled “How Weather Affects Fish Activity“. Check this out if you’re into fishing, it has some interesting info on fishing weather!
Here are a few other photos I snapped at the lake (last one shows two Mallards and a Sandpiper on the left):

A trough is currently moving across the central U.S., with a ridge over the western part of the country.
A low-pressure system is moving into the Northeast, bringing a lot of rain around and ahead of the system and some snow behind it.
The cold front extending south of the low passed through Oklahoma last night (see image below), lowering our temperatures with the arrival of a strong north wind.
This weekend, more heavy rain is expected across parts of the Midwest and some thunderstorms are possible from Ohio to Kentucky. The Weather Channel forecasts that much of this area may see 1.5 to 2.5 inches of rain, with some locally heavier amounts.
Colder air moving into Wisconsin, northern Illinois and Indiana, and Michigan will allow snow a couple inches of snow to fall and possibly even some freezing rain and/or sleet.
Much of the Southeast also is/will be experiencing rain and some thunderstorms today, though flooding is not expected to be as bad as in the Midwest.
As the low moves into the Northeast, wintry precipitation will fall today across parts of the New England area, with rain falling in Pennsylvania and New York.
As for the West Coast, rain will continue to fall in western Washington, western Oregon, and northwestern California. Some snow showers are possible in eastern Oregon and Washington into the northern Rockies. The Southwest, under high pressure, will be warm and sunny.

The Iditarod starts tomorrow, the nearly 1,150-mile trek across southern Alaska for sled dogs and mushers. I’ll be posting occasional info about the race and the weather in Alaska over the next week. To begin with, here’s a map of the race and the National Weather Service forecast for this weekend’s weather in Anchorage, where the race starts at 10 am local time tomorrow.
National Weather Service Anchorage forecast:
Saturday…Partly cloudy. Highs in the lower to mid 20s. Light winds.

This beautiful image was taken recently by a NASA MODIS satellite (click to enlarge).
Anyone want to venture a guess as to what we’re looking at (location and/or feature)?
I’ll post the answer in the comments after 8pm Central Time.

Yesterday marked the beginning of meteorological spring. This is also about the time when climatologically, tornado season begins to pick up.
Here are a couple of plots from the Storm Prediction Center, showing where we are so far this year on tornadoes.
Through the first couple months of the year, there have been 53 tornado reports, which is below the 6-year running average.
The following graph shows the trend in local storm reports (LSR) of tornadoes in the U.S. Values may be a little higher than the actual tornado count (some tornadoes may have been reported more than once). The last six years are shown, as well as the current year up through February 28.
Now look at the graph below (click to enlarge), also from the Storm Prediction Center. This plot shows annual tornado trends; if you’re curious as to how exactly the trends were calculated, see the website on the bottom of the figure. Basically, the red line is the maximum tornado count in a single year and the pink line is the minimum tornado count in a single year. The other lines show tornado trends in quartiles. Currently, 2011 is just above the lowest 25th percentile.
Note the estimated number of tornadoes for 2011 so far is 43 (adjusted downward from the storm reports), though this value is not necessarily the same as the confirmed number of tornadoes.
