My monthly mean low temperature forecast is 17 degrees or +1 degree from the normal. January Summary… It will start off mild in the first few days of January and then a big cool down with snowy and even some lake effect snows. Colder by end of the month.

Models for WNY… Buffalo Local Maps

National Model Maps 

January 2013

500 MB Heights Notice the trough in the Great Lakes Region and the Ridge in the West. This indicated a +PNA and a somewhat –NAO and even a –AO

500 Height Anomaly Look at the red near the Western Greenland. This is the blocking pattern that may set up a stormy one for the Northeast and East Coast. Cold air will filter in underneath this positive height anomalies and bring colder air for the Eastern US.

This is the foretasted departures of the  850 MB Temps for January. Notice the warmth in the East I feel this is over done and will need to be taken down. In the Northeast and Great Lakes Region may see below normal temperatures based on the previous maps.

This is the 70 MB Relative Humidity Forecast Anomalies. It seems to be drier than average due to the cold weather.

February 2013

Look at the trough in the East and a ridge just off the East Coast and in the Gulf of Alaska and Northwest.  This tells me that the PNA will be Positive and the NAO will be strongly negative. In a nut shell cold in the East; Warm in the West except in the Southwest where a bit of split flows will take shape.

It even shows up here on the temperature anomalies at the 850 MB Level. I expect a bit colder than normal in the North East Too. Warmer than what is being said in the Northwest.

 Notice the higher than normal heights in the Northern US. This tells me that there is blocking taking shape off the East Coast. Meaning more storms in the East and Western US.

Even the 700 MB RH is showing wetter than normal in the East and West.

March 2013

Big trough in the Eastern and Mid-West Regions. A Big Ridge in the West. This shows me that much colder air for the East.

It is even showing here on the 850 MB Temperatures Anomalies. I have a hunch that the Northeast and Mid-West will be colder than normal during this time.  Stay Tuned.
