monsoon update... (pm.25.jun.17)>

The latest from the India Met Department:

"Favourable conditions are developing for further advance of southwest monsoon into some more parts of north Arabian sea, Gujarat state, Madhya Pradesh, remaining parts of Bihar and some more parts of East Uttar Pradesh during next 48 hours. Also, rapid advance of southwest monsoon is very likely into most parts of northwest India, including remaining parts of Gujarat, Madhya Pradesh and Uttar Pradesh, entire Haryana, Chandigarh & Delhi, Punjab, Uttarakhand, Himachal Pradesh and Jammu & Kashmir during next 4-5 days. This is expected, in view of the likely west-northwestwards movement of the low pressure system which is currently located over northwest Bay of Bengal & neighbourhood, towards northwest India and its likely interaction with an approaching Western Disturbance."

drying out a bit... (pm.22.jun.17)>

Thursday's stats:

Low temp: 58.1F (14.5C)
High temp: 67.6F (19.8C) -- updated @ 840pm
Rainfall: 0.14" (4mm)

This beautiful evening is quite a gift, considering what we have been through the vast majority of the time during the past six days.  It is partly cloudy and pleasantly cool during this hour before sunset, with much drier air in place across our area.  The morning was not great... lots of clouds were still hanging around, along with several periods of very light showers, sprinkles/drizzle... which didn't really break up until the early afternoon.  For the third day in a row, temperatures have failed to reach 70ºF/21ºC.

An expansive pool of unseasonably cool air aloft drifting in from the north-northwest, crashing into the first major push of tropical moisture advancing from the south-southeast has been the main driver of our extremely wet weather since last Saturday.  But that combination of factors is just now starting to fall apart, as much warmer air in the upper atmosphere begins to push in from the west, while the deeper moisture retreats back to the south for a few days.  That should set us up for some better weather as we head into the weekend, and depending on which set of computer model data is to be believed, this relatively drier and calmer and more pleasant weather could last until about Sunday at the earliest, or Tuesday evening at the latest.  That's when we will see another aggressive surge of juicy tropical air heading in our direction.

Temps will probably rebound nicely on Friday and Saturday, as long as we don't get too much cloud development to spoil the show.

too much too soon... (pm.21.jun.17)>

Wednesday's stats:

Low temp: 57.0F (13.9C)
High temp: 65.4F (18.6C)
Rainfall: 5.21" (13.2cm) -- largest daily total of 2017

Today's rainfall was totally off the charts and beyond comprehension  -- most years during the monsoon season we get a calendar day total in the range of what we saw today only a few times.  In fact, last year, the largest daily rainfall amount of the entire season was on the 11th of August when I recorded 6.17" (15.7cm).  And the best part of the story is, according to the India Met Department, IT'S STILL NOT OFFICIALLY MONSOON.!!  Except for a few very short breaks, it rained almost continuously today from 2:20am until about 3:45pm.

There are indications that we'll see somewhat of a stabilizing trend in our atmospheric dynamics between tomorrow (Thu) and Saturday, though we still can't rule out at least a couple of periods of showers/thunder during that period.  This inaugural surge of tropical moisture will be in retreat mode, while temperatures aloft warm up significantly, especially on Friday and Saturday.  However, a fresh push/surge of very moisture-laden air will be heading in our direction again Saturday night or Sunday, and is expected to hang around into at least the middle of next week.

monsoon flirtation... (pm.20.jun.17)>

Tuesday's stats:

Low temp: 60.3F (15.7C)
High temp: 69.0F (20.6C) -- coolest high temp since 10 april
Rainfall: 1.57" (4.0cm)

Largest daily precipitation totals of 2017:

1 -  2.32" (5.9cm)     19 June
2 -  1.78" (4.5cm)     13 June
3 -  1.70" (4.3cm)      7 January
4 -  1.57" (4.0cm)     20 June (today)
5 -  1.54" (3.9cm)     26 January

Today has been the fourth wettest day of 2017.  Officially, the leading edge of this year's monsoon is still very far to our south and east, but we have been getting our first tastes of the incoming season since Saturday.
