QUICK UPDATE TO INCREASE MORN POPS SIGNIFICANTLY ACROSS PORTIONS

.PREV DISCUSSION...345 AM MDT TUE MAY 21 2013...
UPPER LOW NE NM TAKING ITS SWEET TIME IN MOVING ACROSS NE NM. DECENT
AREA OF LIGHT TO PERHAPS MODERATE RAIN NEAR AND A LITTLE WAYS N OF
THE TUCUMCARI AND LOGAN VICINITY WITH SOME PATCHY LIGHT RAIN...NOT
MUCH LIKELY REACHING THE GROUND...EXTENDING SOUTH AS FAR AS NE
CHAVES COUNTY AS OF THIS WRITING. THIS AREA SHOULD NOT LAST MORE
THAN 2 TO 4 MORE HOURS...BUT DID NEED TO INCREASE LOW POPS ACROSS
PORTIONS OF E CENTRAL AND NE NM. THIS LOW WILL STILL EXIT THE
AREA LATER THIS MORNING. FRONTAL BOUNDARY STILL DROPPING S AND A
LITTLE TO THE W ACROSS THE THE E CENTRAL TO SE PLAINS INTERFACE.
THIS FRONT WILL WASH OUT FOR THE MOST PART LATE TODAY AND THE LOW
LVL MOISTURE THAT WAS BROUGHT IN WILL MOSTLY SCOUR OUT. ANY
MISERLY AMTS OF RESIDUAL MOISTURE MAY BE ENOUGH TO SPARK A FEW
SMALL SHOWERS AND STORMS ACROSS THE N CENTRAL AND MAINLY NE NM...
BUT NOTHING REALLY MAJOR. SOME UPPER LVL RIDGING STILL LOOKS IN
PLAY FOR WED...WITH WARMER AFTN TEMPS...AND ALSO LIKELY TO BE THE
LEAST LIKELY PRECIP DAY OF THE WEEK.

THU INTO AT LEAST THE WEEK WILL BRING THE DIURNAL DRY LINE
SLOSHOMATIC...GENERALLY PUSHING WESTWARD AT NIGHT INTO MAYBE MID
MORN BEFORE BEING PUSHED BACK EAST LATER IN THE DAYLIGHT HOURS.
SOME STRONG OR EVEN A FEW SEVERE STORMS WILL BE POSSIBLE. THE
DRY LINE WILL CONTINUE TO SLOSH BACK AND FORTH OVER THE WEEKEND...
BUT MODELS STILL DIFFER TO A DEGREES JUST HOW FAR EAST IT WILL
MIX OUT DURING THE DAYTIME HOURS. EARLY NEXT WEEK THE IS MORE
AGREEMENT THAN NOT THAT IT WILL BECOME LESS ACTIVE PROBABLY BE
HELD A LITTLE FARTHER EAST NEAR THE STATE LINE.

OVER NEW MEXICO BY WEDNESDAY...AS CLOSED LOW PARKED OVER THE PACIFIC
NORTHWEST SITS AND SPINS...WITH CIRCULATION COVERAGE EXPANDING
STEADILY AS THE WORK WEEK WEARS ON. RIDGE AXIS WILL SHIFT EAST OF

INVADE THE NORTHEAST THROUGH THIS AFTERNOON. DAYTIME MAXIMUM
TEMPERATURES WILL RUN A DEGREE OR TWO SHY OF NORMAL FOR MOST
SPOTS...WITH SHOWER COVERAGE ASSOCIATED WITH THE FRONT REMAINING
SCATTERED OVER THE NORTHEAST. LITTLE CHANCE FOR WETTING RAINS IN ANY
OF THESE SHOWERS. A FEW AFTERNOON WEST TO SOUTHWEST BREEZES OVER THE
NORTHERN MOUNTAINS AND ADJACENT EASTERN PLAINS...WITH GUSTY AND
SHIFTING WINDS NEAR HIGH BASED CONVECTION AND ASSOCIATED VIRGA LATE
THIS AFTERNOON. CONTINUED VERY DRY...WITH MINIMUM HUMIDITIES FALLING
BACK INTO THE SINGLE DIGITS AND LOW TEENS WEST AND SOUTH AND ACROSS
THE RIO GRANDE VALLEY...UPPER TEENS AND 20S OVER THE NORTH AND EAST.
NO VENTILATION ISSUES...WITH POOR TO FAIR HUMIDITY RECOVERIES IN
MOST SPOTS...AND GOOD NEAR THE TEXAS BORDER.

FOR WEDNESDAY...RIDGE AXIS SQUARELY OVER THE STATE AS SURFACE LOW
DEEPENS OVER THE EASTERN PLAINS...SQUASHING DOWN CONVECTION TO
SPOTTY AND ISOLATED MAINLY OVER THE NORTHEAST HIGHLANDS AND
NORTHEAST PLAINS THROUGH WEDNESDAY EVENING. AFTERNOON SOUTHWEST

TO THE CONTINENTAL DIVIDE BY LATE WEDNESDAY AFTERNOON WITH CONTINUED
ROCK BOTTOM MINIMUM HUMIDITIES PRETTY MUCH STATEWIDE. CRITICAL FIRE
WEATHER CONDITIONS FOR GUSTS AND LOW HUMIDITIES STARTING TO EXTEND
INTO NEW MEXICO FOR WEDNESDAY AFTERNOON...AND THIS WILL NEED
WATCHING GOING FORWARD FOR POSSIBLE FIRE WEATHER WATCH. BROAD
WARMING TREND WILL PUSH TEMPERATURES 3 TO 8 DEGREES ABOVE LATE MAY
NORMALS. NO VENTILATION ISSUES WITH POOR TO FAIR HUMIDITY RECOVERIES

AFTERNOON REGULAR VISITOR...AS MINIMUM HUMIDITIES REMAIN IN THE
SINGLE DIGITS AND TEENS OVER ALL BUT THE EASTERN TIER...WHERE INFLUX
OF MOISTURE FROM THE EST WILL KEEP MINIMUM HUMIDITIES IN THE 20S
PCT. TEMPERATURE PROFILE RUNNING STEADY 5 TO 10 DEGREES ABOVE LATE
MAY NORMALS. DEEPENING SURFACE TROUGH FROM EASTERN COLORADO ACROSS
THE EASTERN PLAINS TO EL PASO WILL SUPPORT SOUTHWEST BREEZES ACROSS
THE CENTRAL AND NORTHERN PORTIONS OF THE STATE ON SUNDAY...TO END
