Weather Pattern Review (Sun, Jan 1 – Sat, Apr 7, 2012)

Good Evening Everyone,

I made some big changes to this blog.  I would like to treat this blog as one that will be a tool for meteorologists and weather hobbyists to aid them in weather forecasting.  What you’ll notice is that I put together several flash videos, where you can view a slide show of the analyses.  There are several major sections, Upper Air, Surface and Upper Air, Temperatures, and Precipitation.  So, each section will contain a flash video.  The video player offers a variety of ways to view the video, such as enlarging the video to full screen.  Its probably best to view the video full screen.  Any questions on how to work the player, please feel free to ask me. 

Upper Air Trends
Background Information: The 500mb anomaly map is an analysis that’s taking a look from 18,000 feet above the ground. These anomaly maps help identify tendencies how ridges (high pressure) and troughs (low pressure formed. Think of ridges as regions of stable weather (i.e., dry, cold or hot regions) and troughs as regions of active weather (i.e., wet and stormy). The shades of yellow to dark reds indicate ridging while shades of blue indicate troughs. Once you see the ridges and troughs, you can begin to outline the placement of the jet stream.

So, let’s check out the last several months on how the pattern has been evolving.  The following is a listing summary of time periods that I took a look at. 
- Past Month (Thu, Mar 1 through Sat, Mar 31)
- This Month (Sun, Apr 1 through Thu, Apr 5)
- 2012 Spring Season (Tue, Mar 20 through Thu, Apr 5)

Surface, Upper Air, and Storm Report Trends

In this section, we’ll take a look at surface low and high pressure anomalies. Basically, the idea here is to see where high and low pressures developed and their persistence.  For the Storm Prediction Center Report maps, I overlayed the jet stream.  Its a rough cut idea to see the position of the jet stream relative to where the severe weather occurred.   

This section will provide analyses of Sea Level Pressure Anomaly and Storm Prediction Center Storm Reports with Jet Stream Overlay maps that will be used in the flash video below.  The following is a listing summary of time periods that I took a look at.  
- Past Month (Thu, Mar 1 through Sat, Mar 31)
- This Month (Sun, Apr 1 through Thu, Apr 5)

Temperatures Trends
This section will provide temperature anomaly trend maps.  The following analyses for this section, plots of record warmth and cold, 30 and 90 day mean anomaly maps.  The following is a listing summary of time periods that I took a look at.
- Past Week (Sat, Mar 31 through Sat, Apr 7)
- Past 30 Days (Tue, Mar 6 through Thu, Apr 5)
- Past 90 Days (Fri, Jan 6 through Thu, Apr 5)

Precipitation Trends

In this section, will provide past week rainfall and snowfall records, river and lake flood stages, mean anomaly plots (30 Day, 90 Day, and Year), and total precipitation needed to end drought.   The following is a listing summary of time periods that I took a look at.
- Past Week (Sat, Mar 31 through Sat, Apr 7)
- Past 30 Days (Tue, Mar 6 through Fri, Apr 6)
- Past 90 Days (Fri, Jan 6 through Thu, Apr 6)
- Year to Date(Sun, Jan 1 through Thu,  Apr 6)
