Feb 29 (Reuters) - 
    U.S. natural gas futures eased on Thursday and were headed for a fourth straight monthly fall on plentiful supplies, although
a bigger-than-expected storage withdrawal offered prices some support for the day.
  
    Front-month gas futures for April delivery were down 0.7% at $1.87 per million British thermal units (mmBtu) at 11:50
a.m. ET (1650 GMT). Prices briefly turned positive after the storage report.
        Prices saw a 7% rise in the previous session, rebounding from its weakest level since June 2020 hit earlier in the week. 
  
    Natural gas prices are still set for a more than 10% decline this month, its fourth straight monthly decline and its longest
losing steak since March 2020, affected by a mild winter that has left stockpiles well above normal, while output remained near
record levels despite an Arctic freeze in January that briefly cut output and sent gas demand to a record high.
    LSEG said gas output in the U.S. Lower 48 states rose to an average of 105 billion cubic feet per day (bcfd) so far in
February, up from 102.1 bcfd in January, but still short of the monthly record high of 106.3 bcfd in December.
    The report "was definitely a little on the friendly side because it was a larger withdrawal than expected, with the market
reacting bullishly to a bullish report," said Thomas Saal, senior vice president for energy at StoneX Financial, adding that a
lack of follow-through buying and an oversupplied market countered the gains.
        "How the weather behaves next few weeks, that'll be the key factor. ... If there is enough weather demand, keeping the
withdrawals up in the 90's-80's, 90s area, that could be friendly because typically in March the withdrawals start to dwindle."   
    
    The U.S. Energy Information Administration (EIA) said utilities pulled a bigger-than-expected 96 billion cubic feet (bcf) of
gas out of storage during the week ended Feb. 23. That was higher than the 88-bcf withdrawal analysts forecast in a Reuters poll.

    LSEG estimated 11 cooling degree days (CDDs) for the week as of Thursday, compared with 9 CDDs on Wednesday.
    "Fundamentals don't appear conducive to a price advance sustainable much beyond this week," energy advisory Ritterbusch and
Associates said in a note.
    "While some supportive tweaks to the 1–2-week temperature views may have spurred some buying, this heating season is becoming
advanced enough to curtail HDD accumulation capable of driving a storage surplus of 600 bcf or more next month."
    Market participants also kept a close eye on a wildfire that ripped across the Texas Panhandle. Several smaller wildfires at
various stages of containment are burning other parts of the state's northern Panhandle, whipped up by fierce winds and hot, dry
weather.
    On the other hand, a third of the U.S. faced the threat of severe weather as strong winds, snow and tornadoes threatened the
Southeast, Ohio Valley and East Coast, while a fierce winter storm bore down on the Northwest.
    Dutch and British wholesale gas prices were mixed, as the market approaches the last month of heating season with ample
inventories and weak demand, and amid supply concerns due to an outage at U.S. Freeport LNG.
