The present above normal temps, specially in Western and Central India is due to the Anti cyclone sitting over North Gujarat and adjoining MP. This creates a lower level stability, and stagnates the air, causing it to warm up. The Ant cyclone (High Pressure) will move a bit to the East (already moved on Wed) and bring above normal temps to MP and Vidharbh.
Winds remain East in Gujrat and in Central India. North winds are lacking in Northern India.
Simultaneously, this prevents the WDS from coming further South. This causes the temps in Punjab, and NW India to rise.
WDs are also scarce and less as yet, due to a ridge in the 200 jet streams over Afghanistan.
Absence of Raossby waves and troughs halts frequent WDS.
Next WD over Hills expected on 3rd and then on 11th Jan.
