LUCKNOW, Jan. 25 -- Uttar Pradesh is set for a brief warm-up as night temperatures are expected to rise by 3 to 5degC on January 27-28, accompanied by widespread rainfall, the meteorological department said on Sunday.

The state had witnessed a sharp drop in temperatures over the past 24-48 hours due to cold, dry winds from snow-covered mountains following the fading of the previous western disturbance. Dense fog is likely in some plains districts on the mornings of January 26 and 27 but will clear as the day progresses.

In Lucknow, daytime and night temperatures fell to 22.7degC and 11degC on Sunday from 25.1degC and 15.4degC the previous day.

Fatehgarh (Farrukhabad) and Basti recorded the warmest day in the state at 26degC.
