The Trough is still with us....

Impressive rainfall late yesterday afternoon (but not even close to the image Rick shared with us about Denver downpours - I'll never be able to get that one out of my mind!). It lasted well into the night - total rainfall yesterday measured 1.13 inches. July total is now 10.15 inches, so we still have a way to go to equal 2008's 15.89 inches. Judging by this latest prognosis, we may be on our way:

..excerpts from this morning's Weather Discussion:

.....A WELL DEFINED AND ORGANIZED MONSOONAL
CIRCULATION CONTINUES IN THE LOWER TROPOSPHERE ...CENTERED ON A BROAD CYCLONIC CIRCULATION OFF THE SW COAST OF MEXICO NEAR 18N106W EXTENDING SE IN A GRADUALLY NARROWING ZONE ALONG COASTAL
CENTRAL AMERICA TO A CYCLONIC CIRCULATION STRADDLING COSTA RICA AND ADJACENT AREAS OF NICARAGUA...PANAMA...AND THE FAR SW CARIBBEAN. DEEP LAYERED MONSOONAL FLOW CONTINUES GENERALLY FROM 08N TO 15N BETWEEN 80W AND 115W...AND CONTINUES TO ABSORB TROPICAL MOISTURE AND ENERGY FROM TROPICAL WAVE MOVING THROUGH THE CARIBBEAN. DEEP CONVECTION WAS OCCURRING IN THIS BROAD ZONE OF MONSOONAL FLOW FROM 06N TO 09N BETWEEN 81W AND 87W AND FROM 07N TO 12N BETWEEN 90W AND 102W. AT THE SURFACE...A MONSOONAL TROUGH IS DESCRIBED ABOVE...WITH EMBEDDED LOWS INDICATED. TPW PRODUCTS SHOW VERY HIGH MOISTURE VALUES IN EXCESS OF 2 INCHES
NEAR THE TROUGH AXIS ALONG THE MEXICAN COAST FROM NEAR MANZANILLO TO THE GULF OF TEHUANTEPEC.

...GLOBAL MODELS CONTINUE TO SHOW THE POTENTIAL FOR TROPICAL CYCLOGENESIS TO OCCUR WITHIN THE MONSOON TROUGH WITH DEVELOPING LOW PRESSURE CENTERS SITUATED IN THESE TWO EXTREMELY WET ZONES. A LOW CENTER OFFSHORE OF MANZANILLO IS FORECAST TO SHIFT SLOWLY W-SW DURING THE NEXT FEW DAYS AND SLOWLY BECOME BETTER ORGANIZED.

At approx. 19N/105W, we seem to be just slightly south of the monsoon trough today.

It's a cool 77F/25C temp at 8:30 AM, with 70% humidity,
Everything is damp, damp, damp but also green, green,
green and pretty darn gorgeous, even with no sun on
the horizon.
