Mumbai: Hot and stuffy, with minimal rains. Sunny periods. Day temperatures around 31/32c. Nights also stuffy. (Probably Scruz IMD station needs re calibration and correction for minimum readings). Pune: Days getting warmer, maybe hot after crossing 30c. Kolkata: Heavy rains expected on Monday and Tuesday. Bhubaneshwar: Rains reducing. Readers from Delhi, Kolkata and other regions please give the actual feedback. Helps in forecasting.
Short term variations, local record hots and colds, don’t mean much, that’s just weather. What matters is long term global trend lines over decades, centuries, millennia, eons, epochs. .
Posted 27th July: Heavy rains lashed parts of West U.P. and Delhi region last 24 hrs. The interaction of UAC embedded in the axis, as explained in the 21st July post here on Vagaries. Meerut saw 74 ms till 8.30 am and 147 mms in 9 hrs after 8.30 am on Friday. Agra saw 115 mms as on 24 hrs ended 26th morning and another 63 mms as on 27th morning.

System not effecting Sindh region of Pakistan. Mumbai: Not much of meaningful rains next few days till the 31st of July, daily about 5 mms of rains expected. Hence, with Scruz still 70 mms short seems difficult in breaking the existing record of touching 2000 mms total before 30th July. The lakes supplying water to Mumbai show a cumulative storage of 1202 Mcum, 82 % and 320 days supply.
Thursday 26th July: It is officially the hottest day of the year so far in the UK with temperatures soaring to 35.1C in Surrey. Northern Ireland, Scotland and Wales saw high temperatures of 26.2-29.4C. The
Met Office says temperatures will keep rising into Friday and the UK's
all-time temperature record of 38.5C (101F) - set in Kent in August 2003
- could be beaten. The July record for the highest overnight minimum temperature is 23.3C
- and the Met Office says that could be surpassed in south-east England
on Thursday. The UK's current all-time record temperature for July stands at 36.7C, which was recorded at Heathrow in July 2015.
"Due to the abnormally warm temperatures, MCC has decided to dispense
with requirement for gentlemen to wear jackets in the Pavilion and
arrive wearing one.
This applies to Members of MCC and Middlesex and their guests."
UK/SEATTLE(US) HEAT WAVE .. 26 July 2018 1) UK has been experiencing a hotter and drier summer than normal with comparisons been drawn to 1976 (though current summer is less hotter than 1976) .. UK has received only 20% (47 mms)of average rains during the first half of this summer (1 June -16 July 2018) with some southern parts receiving only 6% of average rains during this window. Half a dozen stations have received less than 1 mm during past 2 months . The 2018 summer rains till now(1 June - 16 July 2018) have been lowest since 1961. This has resulted in below average water content in some of the reservoirs and the generally green countryside has turned brown. Rains(thunderstorms) are expected in UK from tomorrow(27 July) as a front moves over the Atlantic to the east . Weekend is expected to be lot cooler and rainy with London max temps expected to fall by 10 c from mid -30 's of today to lower 20's by Sunday 29 July. Min temps are expected to fall by 5 c (from higher teens to mid teens). The temps are expected to rise gradually next week to touch 30 c by next weekend .
Click on the UK map below to see past 24 hrs max/min temps in c (LONDON avg July temp is 24 c/14 c )
In the London underground metro (tube), commuters have reported 35c to 40c temps with hum around 50% ,causing discomfort (heat index upto 45 )as most of the lines are non air-conditioned.

2) THE US NORTHWEST COAST (Seattle) .. The US northwest coast is mirroring the UK summer season with a hotter and drier summer than normal . Seattle average temp for July is 24 c / 14 c (19 c mean). It's one of the least air-conditioned city of US. The warmest mean summer temp has been 21.8 c in July 2015 . It needs to be seen whether July 2018 will break this record with above average temps till month-end as a high pressure ridge remains stubborn because of the jet streams meandering north than usual (like UK).
Spokane (Columbia Plateau) is hot and dry at 34 c (+6) /18 c (+4) . Click on the Washington state map below to see past 24 hrs max/min temps in c
Friday, July 27th, is a big night for astronomy. Three reasons: First, Mars will be at opposition--directly opposite the sun and making a 15-year close approach to Earth. Second, Mars and the full Moon will be in conjunction--less than 10 degrees apart. Third, the Moon will pass through the shadow of Earth, producing the longest lunar eclipse in a century:
Almost everyone on Earth (except North Americans) can see the eclipse as the sunset-colored shadow of our planet swallows the Moon for almost 2 hours. During totality, the Moon will turn almost the same red color as Mars right beside it--an incredible sight. Because Mars is opposite the sun, it will rise at sunset and stay up all night long. The best time to look is around midnight when the Moon-Mars pair will be at their highest in the sky. The Red Planet will have no trouble being seen through the glare of the full Moon because Mars itself is so luminous--almost three times brighter than Sirius, the brightest star in the sky.
Is Mumbai in for the fastest 2000 mms ever ? Will it beat the previous record of 60 days this year ? The total today stands at 1927 mms...Short this year by only 73 mms and 7 days to go to beat the record for fastest ever total of 2000 mms !
let's see, the wettest July ever for Scruz was in 2014 when July
recorded 1469 mms in the month. The
current record for the fastest 2000 mms at Santa Cruz was in 1965, when
it touched 2000 mms on 30th July, in 60 days. Followed by 2005 when the
total was surpassed on 31st July, in 61 days.
just for the records, has crossed 2000 mms by July 3 times. In 1886,
1907 and 1991. Colaba has managed the seasonal total at 1517 mms. this year...no question of any records.
Posted 21st July Saturday Night: BB-5, as a Depression, has crossed the coast at 21.8N and 87.1 E near the Odisha/West Bengal border. As can be seen from the Satellite image , super-imposed on IMD image, the maximum effect of rainfall and clouds are seen in the Western quadrant of the system. Core estimated pressure is 993 mb. Outer periphery winds are around 40 kmph.
System will track NW and weaken, initially at the surface level and remain as a UAC for another 2 days. As the system tracks NW, along the Monsoon axis corridor, the rains will move across Chattisgarh and Bihar (much needed) and U.P., and gradually weaken in Odisha. Tuesday onwards the NW plains including Delhi and Haryana will get heavy rains. Vidharbha region may get good rains on Sunday 22nd. An Upper air axis will hence form from North Gujarat to U.P. Inter action with another embedded UAC will bring good rainfall to Rajasthan, North India plains in 2 days from Saturday (next week). For Pakistan most of the rainfall, the major part, from BB-5 is seen in the North and Upper Central regions from Monday. No major meaningful rains in Sindh. Break Monsoon conditions may prevail after 26th as BB-5 moves into the Himalayan foothills. Meaning, widespread rains in Uttarkhand, U.P. and NE States. Break Monsoon conditions will reduce rains in the Central Indian region, and Peninsula. Delhi NCR: Heavy rains will commence on Tuesday 24th and continue thru Wednesday and Thursday. Day temperatures Thursday can drop below 30c. Mumbai: : Sunday 22nd and Monday 23rd: Very windy. Occasional passing showers, some heavy. Days may be interspersed with bright periods. Tuesday: Decrease in rainfall amounts with partly cloudy skies. Substantial decrease in rainfall after 26th July.
Surat: Chances of heavy rains on Monday 23rd and Tuesday. Decreasing thereafter.

Posted 13th July Night: As posted on 9th , The Low pressure has formed in the North West Bay. It has been long since we saw a system from the Bay, only numbered BB-4 . This has kept the Monsoon trough in its normal position. As Vagaries had mentioned in the 10th post, Being active along the trough, Delhi region got very good rains on Friday. From 8.30 am- 5.30 pm, The Ridge saw 118 mms, Ayanagar 71 mms, Lodhi Road 44 mms, Gurgaon 39 mms.S'Jung 5 cms. Rains reducing after Saturday, to increase again next Wednesday. Mumbai: After a few showers on Friday, we see a gradual increase in rainfall from Saturday. Frequent showers on Saturday increasing to frequent showers with increased rainfall on Sunday and Monday.With rainfall likely around 100 mms or more in some Northern suburbs, Local flooding possible on Sunday/Monday. More rains likely in Northern outer townships and ghats.
Wet July (10 days) for Mumbai this Monsoon. Santa Cruz received 869 mms of rain in the first 10 days of July. The season's total now stands at 1662 mms. Well, let's see, the wettest July ever for Scruz was in 2014 when July recorded 1469 mms in the month. 600 mms more to catch up in 20 days ! The current record for the fastest 2000 mms at Santa Cruz was in 1965, when it touched 2000 mms on 30th July, in 60 days. Followed by 2005 when the total was surpassed on 31st July, in 61 days.
Is Mumbai in for the fastest 2000 mms ever ? Will it beat the previous record of 60 days this year ? Short this year by 338 mms and 20 days to go to beat the record for fastest ever total of 2000 mms !
Colaba, just for the records, has crossed 2000 mms by July 3 times. In 1886, 1907 and 1991. But, we are still way behind for this station to cross 2000 mms by July end.603 mms to recover stilll for the fastest 2000 mms.
Colaba has managed 609 mms in July this year, with the seasonal total at 1397 mms.
