When was the last time you saw the Jet stream dive to Southern Mexico???? And when was the last time Texas was "too far north" for snow?!
Also notice the streamline flow from the Pacific to the Eastern U.S.
I bet Florida wishes the Jet Stream would dive that far south. Get an Upper low like that over the Gulf States and it will.
But an Upper Low in the West has different results than the East. You will get more extreme cold in the East because there is typically more Canada interaction than Pacific.
I mean the flow is still off the Pacific and into Mexico right now even with an Upper Low. But still... its cooler than normal and there is mountain snow in Mexico!

THE FIRST SYSTEM IS CURRENTLY DROPPING SOUTH ACROSS NORTHERN
MEXICO. THIS TROUGH WILL PASS TO OUR SOUTH KEEPING THE BEST DYNAMICS OVER NORTHERN MEXICO. SOME OF THE MOUNTAINS OF NORTHERN MEXICO COULD SEE SOME DECENT SNOW TOTALS. WHO KNEW WE WOULD BE TOO FAR NORTH TO GET MUCH SNOW. FOR US THE MAIN THREAT WILL BE
ISOLATED TO SCATTERED RAIN SHOWERS IN THE LOWLANDS AND SCATTERED
LIGHT SNOW SHOWERS IN AREA MOUNTAINS. RIGHT NOW SNOW LEVELS WILL
START OFF AROUND 8K FEET BUT WILL DROP TO AROUND 6500 FEET BY
TONIGHT...SNOW TOTALS...THOUGH...WILL BE GENERALLY LESS THAN 3
INCHES.

...Severe thunderstorms and flash flooding possible for portions of the
southern plains and lower/middle Mississippi valley...
...Rain and mountain snow expected for northern California and the Pacific
Northwest...
...Well above average temperatures expected from the Midwest to the
Northeast...
A large and anomalous upper-level low is digging into northern Mexico this morning, and will slowly move southeastward through the next couple days.
At the surface, a low pressure system associated with the upper-low will
move into western Texas by late this afternoon. A warm, moist, and
unstable air mass across the southern plains and Mississippi valley ahead
of this system will result in the development of widespread showers and
thunderstorms today from the southern plains to the Great Lakes. Some
thunderstorms may become severe across portions of the southern plains,
where the Storm Prediction Center is forecasting a slight to enhanced risk
of severe thunderstorms. Additionally, flash flooding is possible across
portions of the southern plains and lower Mississippi valley. On Wednesday
and Thursday, the axis of shower and thunderstorm activity will shift
slightly eastward each day, with many of the same areas receiving
widespread showers and thunderstorms. Excessive rainfall amounts of 5 to
10 inches, with locally higher amounts, are forecast across portions of
the western Gulf Coast, southern plains, and lower Mississippi valley
through Thursday morning, with additional rainfall possible during the day
on Thursday. The potential for multiple days of heavy rainfall across the
southern plains and lower Mississippi valley will result in an increasing
threat of flooding and flash flooding through mid-week.
A cold front will spread rain and mountain snow into the Pacific Northwest
and northern California today. This system will weaken tonight into early
Wednesday morning as it moves inland, bringing scattered areas of rain and
snow to the Intermountain region. During the day on Wednesday, a stronger
Pacific low pressure system will approach the northwestern U.S., once
again spreading rain and mountain snow into the region. This round of
precipitation will continue into Thursday.
High pressure at the mid and upper-levels of the atmosphere will promote
well above average temperatures through the next couple days from the
Midwest to the Northeast. Afternoon high temperatures today are forecast
to be 15 to 30 degrees above average across the Midwest and portions of
the Mid-Atlantic. The warm temperatures will expand into the New England
on Wednesday.
The Euro says don't count on a cool April..... Torch continues...
Well, darn.
I was hoping we could have an April colder than the past December for the first time since records have been kept. But we need one of the 9 coldest Aprils on record for it to happen.
