After crushing us December through February, winter has gone away with barely a whimper this March. So far this month, we've reached 50 or better every day except March 2, 3 and 4 that's 13 out of 16 days. Recall we hit 50 just once the entire month of February. Last March was much fiercer by comparison, when we only made it to 50 or higher on 6 out of the first 16 days, with a streak of 5 consecutive days in the 40s March 12 16.

Keep reading for more on the rapid switch http://www.packersnflofficial.com/Nike-Micah-Hyde-Jersey.html to above average temperatures this March.

For the last 12 days temperatures have been above average. Even our recent cloudy and cool stretch (Friday through Monday) ended up above average (each day) because of relatively mild nighttime lows. Amazingly, the temperature has not dropped to freezing at National Airport (DCA) the entire month. The last time it hit freezing was Feb. 27 (when it dipped to 31 http://www.packersnflofficial.com/Nike-Andrew-Quarless-Jersey.html degrees). Last year on the other hand, we had three straight nights in the teens in early March (March 2 4).

Might we not experience Elite Haloti Ngata Jersey a freeze the entire month of March at DCA? It's possible, as mild weather is expected for the next five days. On the other hand, there is some indication of a shot of cold air next week.

For those who consider winter over according to the meteorological definition of March 1, this year's weather certainly supports that notion based on the observed weather of March 1 16 and the forecast weather of March 17 20. Of course, by saying that, we'll probably get a blast of cold and/or snow to end the month (as in 1891 and Nike Haloti Ngata Jersey 1942: March is fickle).

For practical purposes the threat of snow is probably gone until Dec. 5, 2010. We could still Jamari Lattimore Jersey get some conversational flurries during the next month, however.

The primary threat this spring will involve hail. Hail is more likely before June 15 because the air at higher altitudes is still cold from the past winter. In fact, the combination of rapid surface warming, moisture advection and leftover cold air aloft during April is what's responsible for the frequent "April showers". Instability precipitation reaches its height next month, and may continue off and on through July since ground heating is strongest under the direct sun at the summer solstice. So far tonight, I am recording the highest temperature at 52(F), while most others are between 44 46(F). At Jamari Lattimore Womens Jersey the same time, my RH reading is around 35%, whereas the other locations with lower temperatures have RH readings of between 60% 80%. I have always noticed that it becomes more humid at night, as opposed to the daytime, especially when temps. are warm, but I've never pondered the relation between Temperature/RH variations such as I am witnessing firsthand now. Could someone please explain what I am witnessing here? I know that the RH generally decreases with daytime sunlight/heating, and vice versa, but I'm simply wondering why my readings are managing to stay drier and warmer than many of the other surrounding spots.

Btw, my low temperature readings often reach roughly the same temps. as the other stations nearby right around sunrise, but it simply takes mine longer to achieve such. I live in a slight gully, with a creek out back, and my station is situated about 15 20 ft. above the ground (5 7 ft. above the surface of the wooden deck (Which is away from any artificial heat sources)). It also has a Passive (Gill) Radiation Shield.
